Apache Fancy Indexing Directory Listing with PHP
by Steven Seiller - 13-Nov-09
Reader Level:

This script lists the contents of files and directories in the Apache Web Server. While Apache has built-in functionality to list files and directories with the FancyIndexing directive, the functionality is limited and the icons are outdated.

This script lists the contents of any directory or sub-directory into which the script is placed for the purpose of browsing, viewing or saving files. It features contextual icons for file types and only list files and directories found within the structure of the script's directory. You can even add your own style sheet to the listings.

It is possible to directly alter the Apache configuration to display listings with your preferred style, but you need root access to the underlying levels of the Web server and advanced knowledge of the configuration. If you have root access, you can also simply change the default icons provided with Apache which is limited in terms of file types. Since many developers do not have root access to their Web server nor wish to muck about in the configuration, this script provides an easy alternative to customizing directory listings.

This tutorial will demonstrate how to use this directory listing script and show you the one line of code which (possibly) needs to be customized for your Web server. You will also be shown how you can customize the script to incorporate your site design, data display and how to implement the configuration on a site-wide basis. Advanced and developing PHP programmers can also explore the functionality of:

reading directories of files
reading file attributes including date, extension, and size
sorting arrays
formatting the file size to human readable display
working with server path and links

PHP Sledgehammer: array_map
by Steven Seiller - 14-Sep-09
Reader Level:

In PHP you have an array of data that you wish to transform with a function. You might be tempted to create a control structure and loop through each value of the array, applying the function as you go. PHP has an easier method for accomplishing this process. It is the sledgehammer known as array_map. I find this function useful, for example, to trim the whitespace from incoming form data.

PHP Undo Delete Button in Dreamweaver

Creating a Form Confirmation Page in PHP
by Tom Muck - 27-Aug-09
Reader Level:

A confirmation page is the last page you reach before submitting a form -- you fill in the fields, click submit, review your information, and then submit one final time. Confirmation pages can be built in different ways. I'll show one method, using PHP, that utilizes hidden form fields to post to your final action page. I'll leave the bells and whistles to the reader (validation, CSS, etc.) and show the meat of the technique that is being used.

File Uploads with PHP - Part 4: Storing File Information in a Database
by Steven Seiller - 31-Jul-09
Reader Level:

So far in this series, we have treated the uploaded file by saving it directly to the filesystem of the web server. So, now what? In most applications where files are uploaded to the server, typically some of the file information is stored in a database.

In this fourth part of the series, we will go deeper into the process of storing file information in a database. This part demonstrates the process of creating a BLOB data field in MySQL and storing uploaded files in it. Also demonstrated is the process of retrieving files from the database and downloading them through the browser.

To handle file uploads, use built-in PHP functionality. File uploads can be integrated in applications such as form submissions, file sharing, image uploads or FTP replacement. PHP features a superglobal array specifically for uploaded files as well as specific functions for handling uploaded files.

Part Three of this script will demonstrate how to limit file uploads based on the size or type of file. These checks will be done with data supplied by the common gateway interface and built-in PHP functions. Also, we'll discuss important security considerations which need to be addressed when limiting file acceptance. Finally, we'll look at reporting file upload errors.

Cartweaver Admin Hints and Mods Part 4: Creating an Order Report Graph for PHP
by Tom Muck - 13-Jul-09
Reader Level:

Cartweaver is an online shopping cart system available from www.cartweaver.com for PHP, ColdFusion, and ASP. It is intended as an easy-to-use solution for building an online store. It doesn't have all the bells and whistles of some of the more pricey carts available, but with a little coding, many new features can be added.

Part 3 showed how to create a simple order graphical report to the Cartweaver admin for ColdFusion. This part will show the same functionality for the PHP version of Cartweaver.

Note that ColdFusion has built-in graphing capabilities, whereas PHP requires the use of a third-party library. This article uses the JpGraph library for PHP, described in this article by Steven Seiller: JpGraph: PHP Graphs & Charts On-The-Fly. Steven's article explains the graphing process. This article will focus on building the report query. The library is readily available and easily installed locally. It requires the GD Image library to be installed into your PHP installation, compiled on a Linux host or included in your extensions directory in Windows. See Steven's article for more information.

Sending Email from PHP in Windows
by Rob Williams - 04-May-09
Reader Level:

One of the most commonly used features of PHP is the mail function (or some class built around it). This handy command allows you to send emails from within your PHP code, providing a wide variety of handy features ranging from client notifications to administrative reminders. However, if you're working on a Windows-based testing server you'll often find that that mail functionality simply doesn't work!

In this article we're going to look at why this is and two easy ways to help remedy the problem.

PHP Output Buffer: The Programmer's Assistant
by Steven Seiller - 27-Apr-09
Reader Level:

PHP's Output Buffering has many useful applications and should be in the toolbox of any advanced PHP coder. In short, PHP can save the output of content to the browser in a temporary buffer until called to use it. Buffering output has many applications inlcuding:

Sending headers such as a cookie after beginning to process a page.
Output at once the contents of a dynamically-built page.
Capturing page content until the script determines where the content will be used.
Capture and re-routing script errors instead of displaying to visitor.
Redirecting page output to a log file or email body.
Conducting string replacement on page content to provide custom mark-up or vocabulary.
Dynamically building images with PHP.
Compressing page output to provide a faster download to the visitor.
Using show/hide logic for verbose content.

Select Random Content with PHP and MySQL
by Steven Seiller - 08-Apr-09
Reader Level:

You want to provide random content from your database to visitors of your web page. This might include random news, products, events or testimonials. How do you select random content from your MySQL database? During the visitor's time on your web page, you wish to not repeat the display of the same content. How do you not repeat the same random content?

In this tutorial, we will use PHP and MySQL to randomly pick and display content to the visitor. For extra credit, we will track the content the user has already been shown and not repeat it. We will also look at a way to further customize the chosen content.

Creating an Alphabetical Directory Listing with PHP and MySQL Free!
by Steven Seiller - 31-Mar-09
Reader Level:

You want to create an alphabetic listing of database records by grouping them by their first letter. As a convenience, you want to provide a menu of alphabet letters with hyperlinks to take you directly to the records for that letter. How do you create an alphabetic listing of database records without performing 26 queries - one for each letter?

I've reduced the process to just one query which first selects the first letter represented by the records and then grabs the data itself. I created arrays for each letter to store data until it is displayed. The script uses a few advanced PHP bits to keep the code concise including:

MySQL substring() function
range() function
array_key_exists() function
ternary operator
variable variables

Easy Dates With PHP DateTime Class

Conditional PHP: Using the Ternary Operator
by Tom Muck - 09-Feb-09
Reader Level:

There are many uses for conditional statements in programming. The basic principle of conditional programming is that you want to execute code based on a certain condition. The essence of conditional programming is executing code based on the condition being true, with an alternate piece of code being executed if the condition is not true. The article will explain the ternary operator, which creates if/else logic that is more concise than other methods.

Creating a Formatted Unique ID in PHP
by Tom Muck - 19-Nov-08
Reader Level:

There are often times that you need a unique id in an application, but don't want to use an auto-incrementing integer. If an application is well designed and secure, an auto-incrementing number is usually fine, but to be on the safe side a unique identifier other than an integer is better as an id. For example, a customer number is a good use of a unique identifier, or an order number.

Build Your Own Contact Forms - Part 4: Spam Prevention
by Steven Seiller - 13-Nov-08
Reader Level:

Preventing form spam can be a fairly simple process with thoughtful programming and error trapping. Most developers use CAPTCHA, those little images with distorted letters which you have to decipher and enter. Other tests might include simple math problems and questions with obvious answers. Personally, I detest those vision tests and feel it is a certain way to turn away potential customers. They are getting so distorted these days, they are almost impossible to decipher. Recently, It took me three attempts to get through one of those!

Here are some effective spam blocking techniques which don't involve vision tests.

Reader Level:

In Part 1, we discussed the purpose of utilizing contact forms and their general workflow. In Part 2, we created the HTML form which is used by the site visitor to enter specific, required information with their request. In this part, we will use PHP to construct a server-side processing script to handle the incoming data, validate it and send email to the submitter.

We'll be using a PHP class to ensure that specific fields have been submitted and to ensure that any email address submitted has valid syntax. To send the email, the PHPMailer class will be employed to make process quick and easy. This class increases form security over the easily exploitable PHP mail function. In our sample script, we'll email the submitted data to a specified recipient and send an email confirmation to the submitter from the specified recipient.

This tutorial will walk through the essentials of processing submitted HTML form data. Whether you are processing information submitted through a contact form, a blog or a content management system, you must understand the essential components of submitted form data in order to process the submitted information. You might process the submitted data with ASP, ColdFusion, PHP or Perl but regardless of the scripting language you choose, the data submitted through the Common Gateway Interface (CGI) remains the same.

In Part 1 of this tutorial, we reviewed the CGI process and the two methods of submitting form data via HTML. Additionally, we will look at the range of form controls at your disposal and the nature of the data returned by each control. In Part 2 of this tutorial, I will use PHP to demonstrate the structure and values of typical form data with sample processing routines.

Dynamically Streaming a File in PHP
by Tom Muck - 11-Jul-08
Reader Level:

There are many ways to create a file download from a web site, however, sometimes it is necessary to hide the physical path of the file. In PHP it is possible to dynamically stream the file to the end user, eliminating the chance that a user can download the file directly. This is often a requirement of an e-store that sells downloadable content, such as PDFs of books, music downloads, or software. This article will show one simple way to accomplish this.

PHPMailer: Full Featured Email Transfer Class for PHP - Part 2
by Steven Seiller - 10-Jul-08
Reader Level:

PHP contains a mail function which sends script-generated email with very little configuration and ease. This built-in function, while easily accessible, provides only basic options for creating emails and requires a more manual effort to create advanced email features such html formatting and attachment encoding.

For many years, I have used PHPMailer which is an object-oriented PHP class that easily allows you to implement advanced email formatting. Features which can be readily tapped include: SMTP authentication, use of redundant SMTP servers, attachments, HTML formatting, multipart/alternative formatting for non-html email and various encoding methods. Due to its ease of use and broad feature base, I incorporate the PHPMailer class into all my scripts which send email.

My primary reason for using this class comes from the ability to send script-generated email through authenticated SMTP servers which dramatically reduce the risk of the email being trapped in spam filters. In my testing, mail sent directly from the server by the mail() is significantly more likely to be caught by ISP spam filters due to the fact that it resembles robotically generated spam. I also enjoy the relative ease of adding attachments, html formatting and using multipart/alternative text for email client preview.

In Part 1, I demonstrated how to install the PHPMailer class and use it to create simple email, while sending through an authenticated SMTP server. Use of this class requires some knowledge of working with server files and directories and some experience with PHP classes.

Here in Part 2, we will take it further and go over adding attachments and creating HTML emails.

Downloading comma-separated value (CSV) results is a common task in web development. If you have an e-store, for example, you may want to download orders, products, or customers. There are hundreds of other uses—search results, school lists, movie titles, book lists, tables of contents, access reports, web stats, etc.

Part 1 of this series showed a basic CSVFile class with the ability to create a CSV file download from any recordset. This part will show how to make a few tweaks in the class to allow Excel file downloads. The class is already built—all you do is call it. The class does not create a file on the server—it simply streams the content to the user as a file, not cluttering up your server or creating files that then have to be deleted. The article builds on the files used in the last part and simply makes a few changes to them.

There are hundreds of other uses—search results, school lists, movie titles, book lists, tables of contents, access reports, web stats, etc.

PHP 5.1 has a new function called fputcsv to write a line to a file, but this article will show a technique that will work in older versions of PHP, and is generally very easy to use using a PHP class I wrote a while back. The class is already built—all you do is call it. The class does not create a file on the server—it simply streams the content to the user as a file, not cluttering up your server or creating files that have to then be deleted. I've found over the years that dealing with files on a PHP server has created the worst nightmares for beginning PHP developers. Setting and maintaining the correct file and folder permissions are somewhat of a black art.

Have you discontinued a product or renamed your service? Do you need to redirect visitors from an old web site domain to a new web site domain? This tutorial will show you how to use Apache server redirection to automatically transfer incoming traffic from the old site to the new. Additionally, we will use a code to tell the search engines about the permanent change so it will update its index.

What the automatic server redirection will not do, however, is inform the visitor of why they suddenly find themselves at a different website. Using PHP, I will show you a second step which will allow you to display a contextual note to visitors about the change. I devised this extra step to enhance customer service and educate longtime visitors about the changeover. Because this information is displayed only to redirected users, it will not distract new or potential customers.

PHP Phreakout: Troubleshooting Tips for PHP Code Free!
by Steven Seiller - 18-Feb-08
Reader Level:

I call it the "White Screen of Oblivion." You've seen it. You just finished your new code and you eagerly upload it to the server to watch the magic you just conjured. You load the script and wait. And Wait. That white, blank screen opens like a void and sucks your confidence while the concept quickly sinks in that you have a problem. Ok, but what problem? Not even an error message?

With experiences like that, we can actually be happy when we do receive an error message. Even one which says fatal. At least an error message gives us a line number and some kind of a clue!

So what happens when your PHP code doesn't work as expected? What do those messages mean? Sometimes confusing, sometimes cryptic, those little blurbs declaring that you goofed can actually be helpful! In this article, I will describe the process and some tricks I use to troubleshoot my PHP code during initial development.

Case Study: How to Customize a JumpStart Free!
by Steven Seiller - 22-Jan-08
Reader Level:

The primary benefits to the JumpStarts are that they have been tested with the popular browsers and can get you up and running quickly. Having a limited timeframe to get the site redesigned, I decided to give the JumpStarts a good look. What I quickly realized is that despite my disdain for templates, the JumpStarts are highly customizable, which can result in uniques designs.

In this tutorial, I will describe the process I used for assessing my web site needs and selecting a specific JumpStart. We will then walk through the steps of creating a unique design from the example. Finally, I will share an extra step I took in which I used PHP to 'templatize' my page design to speed content creation, ease revisions and provide customized content to the visitor.

Using Quotes in PHP

The Secret Art of Cookies: Part 2
by Rob Williams - 15-Nov-07
Reader Level:

Preserving data for an end user can be one of the more challenging tasks when you first start to learn a server-side programming language like PHP. Sessions are a good starting point that allow you to carry information about users across multiple pages of your site, but alone they can fall short of expectations as they are always only limited to the length of a current browsing "session".

In the first part of this series we looked at what cookies were, how easy they were to use, and some of the general pitfalls that developers need to be aware of when utilizing them. Today we're going to focus on setting the record straight on cookie security and the realities of using cookies in your own web applications.

Creating a Redirected Login
by Rob Williams - 06-Nov-07
Reader Level:

Creating a two-tier web site is a task that most developers have to deal with regularly; often times a site will require both a public and "member's-only" section. Although there are many tutorials and explanations of how to use databases to build and manage login systems, one of the questions that I find often goes unanswered is how to make your login page "transparent".

In this article we'll take a look at the theory and a simple implementation of how you can go about presenting a login page anytime a user is directed to "member's-only" content and, most importantly, how to continue sending them to their desired page once the login is complete.

Controlling the Serial Port with PHP Free!

A Simple Error Handling Function for PHP
by Tom Muck - 24-Sep-07
Reader Level:

Error handling is an important aspect of site development, but using PHP there aren't too many clearly defined ways to handle errors. I will present a simple function that handles errors in several ways: records the error in a log, emails the site administrator a copy of the error, and redirects the user to a central error page. Using one or more of these three methods, you can handle errors more gracefully in your PHP pages.

Creating a Master/Detail Pageset on One Page Using AJAX
by Tom Muck - 19-Sep-07
Reader Level:

Dreamweaver's Master/Detail page set is a handy set of behaviors to use for a drill-down functionality -- display a list of records, and click on a link in the list to view the full record. Using the behaviors, however, you typically create two pages. If you create one page with both, the page will refresh each time you click on a link.

In this tutorial, I'll show how to create one master/detail page that uses some very simple JavaScript to load the details section of the page dynamically using AJAX. This tutorial will apply to PHP, ColdFusion, and ASP, with the concepts applicable to the other available server models that Dreamweaver now supports.

PHP Sessions - Keeping Data Over Multiple Pages
by Rob Williams - 24-Aug-07
Reader Level:

One of the age old problems with server-side scripting is that it's based on a page-by-page production model; that is, each page is interpreted and run as its own entity as the user requests it. While this makes development more inline with traditional HTML, it also makes it more challenging to create full-fledged applications that may span multiple "pages" of a site.

If you're new to PHP (or indeed most server-side languages) the desire to have variables or data persist across multiple pages has probably arisen several times, but a straightforward explanation of how to do this is often overwhelmingly difficult to find. The purpose of this article is to provide with practical knowledge of both the theories and actual code that you need in order to carry data across multiple PHP pages.

Creating a Simple Database Web Search - Part 2: PHP
by Tom Muck - 13-Aug-07
Reader Level:

In the first part of this series, I showed how to create a Master/Detail page set using built-in Dreamweaver tools, and then add a basic search form querying against one field in the database. What if you want more than that though? The Dreamweaver recordset dialog box allows one filter against one field. This is sometimes useful, but usually not. Typically you might also want to allow other HTML fields into the search. You will want to search allowing multiple search words. Finally, you might want to search multiple database fields.. I will address all three situations in this article, which will be targeted to PHP users only.

Custom PHP Settings With .htaccess
by Rob Williams - 03-Aug-07
Reader Level:

Every now and again I find as a web developer that there are times when the default PHP configuration on my server just isn't working as well as I'd like it to for a given project. This can be especially plaguing when you're dealing with remote web hosts that offer you little to no control over the configuration of PHP itself. Anytime you're running multiple web sites off the same server this can also be a problem as you may want to have different PHP settings for each of the sites.

In this article we're going to take a look at one possible solution to these problems by including PHP configuration values within an .htaccess file.

Create a Table-less Horizontal Looper in PHP
by Tom Muck - 05-Jun-07
Reader Level:

Dreamweaver has a Repeat Region server behavior that loops through your data and allows you to display it in a vertical or horizontal manner. If you want to display the data in a grid pattern, however, it requires a little more effort. Typically, a Horizontal Looper extension or code is used to create a table and put your individual data sections in a table cell. In this tutorial, I'll show how to do that using <div> tags and CSS without tables.

For this tutorial I'll assume you know how to use MySQL tools to create and manage databases, and how to create connections for PHP in Dreamweaver.

Anti-Spam Measures for PHP and ColdFusion - Part 2

Reader Level:

Spam, spam, spam, spam. Spammers have taken over the Internet and made it a horrible place to maintain a web site. Spammers have gone beyond simply spamming your email account -- now they are spamming blogs and guestbooks, spamming trackbacks, and spamming signup forms. Even a child's home page with a guestbook for friends is not safe from links for cialis, porn, or web hosting. Obviously these spammers are getting some return from their criminal activity, because they keep doing it. Unfortunately, you can't reach through the computer screen and grab them by the throat to strangle the life out of them. All you can do is put in place some safeguards and try to minimize the attack. Part 2 in this series shows how you can record the IP address of the spammer and block access to your site to that computer in the future. Once again, I'll assume you have familiarity with PHP or ColdFusion basics (databases, inserting and displaying data) and HTML forms.

Server-side includes are one of the most important concepts for web developers today. They not only save you time but also make sites easier to update and maintain while reducing redundancy and duplicate pieces of code. The cavet that most new developers run into is that although the idea of server-side includes in general seems quite simple, often the implementation can be quite frustrating if not planned out correctly. In this article we'll talk about not only the theory, but also some practical examples, of how to properly implement server-side includes using PHP.

The Lost Art of PHP Control Structures - Part 6: Resource Pointers and One Last Trick
by Rob Williams - 31-Jan-07
Reader Level:

One of the key components of any scripting or programming language are control structures; statements that tell a language interpretter to stop reading code in a linear line-by-line fashion and start to make more complex operations based on simple logic. While most developers are aware of the common "if else" and "for" structures, there are many others available in PHP (and other languages I might add) that allow you to save a great deal of time and make your coding more efficient and easier to understand.

In this series we're going to take a look at some of those "forgotten" structures and some practical examples of how they can be used to clean up your coding techniques. In the final part of this series we'll tie up some loose ends and take a look at one last neat little trick: resource pointers.

Sometimes dynamic code can have advantages when it comes to adding some aesthetic features to a web design. In this example we will build a small PHP function that will output a different CSS link to your pages depending on what time of the day it is. We will also have a look at the best way to deploy this technique in terms of CSS.

We will take advantage of PHP's date function and switch statements to make our function work.

The support files download for this tutorial contain a nice looking example of a CSS header image rotation based on the time of day. It's complete with the 4 PNG files used, CSS files, PHP function and test page.

Reader Level:

When you look around the internet you will find a multitude of community-style sites that offer their visitors the opportunity communicate via a real-time chat application. Many of those applications are cumbersome and rely on terrible page refreshes every few seconds.

The fact that chatting online is a very important part of building friendship and communication within a community web site makes it no surprise that a frequently asked question on web development forums is "How do I add live chat to my web site?". It's a common question with so many possible answers.

In this tutorial I will introduce you to a free PHP chat application that works in modern browsers and degrades gracefully in the not so modern browsers that some people still persist in using.

This application is special for a number of reasons. To find out just how special it is please read on.

Implementing Gravatars with PHP
by Gordon Mackay - 13-Sep-06
Reader Level:

What with all those blogs, forums, galleries and other applications that allow web site users to add their own comments on pages it was little wonder that someone decided to create universal method of graphically identifying users.

Gravatars are an adaptation of the good ole' fashioned forum "avatar". The main difference with Gravatars is that they are served from a single place, instead of individual servers. The idea being that no matter where you're posting comments, your avatar will always be the same. Also when you change the image it changes everywhere you have left a comment too! Cool huh?

Let's say you have created an application in PHP and you wish to allow your users to take advantage of Gravatars. How would you do this? Let me show you the easiest method.

Fortunately, a special set of tools commonly called "regular expressions" can often save you a great deal of time and effort, helping you achieve goals that you never thought possible. The downside, of course, is that you have to learn how to use these "expressions", and they can be quite confusing at times.

In this article we'll take a beginner's look at what regular expressions are and see through examples how they can help you in your day to day tasks.

PHP Formmail Spam Prevention
by Sheri German - 25-Aug-06
Reader Level:

It used to be that there were clear sides in the junk email battle: the spammers and the spammed. I always considered myself a member of the latter group, and then one day I became a member—inadvertently—of the former. I had become a victim of the email injection attack via a PHP formmail script.

In this update to the Dreamweaver Creating and Processing Form series, we'll take a new look at the phpformmail script and demonstrate how to use a key and email value pair to keep your email address out of the html page.

Tag Clouds with PHP and MySQL
by Gordon Mackay - 15-Aug-06
Reader Level:

Tag clouds are all the rage these days when it comes to browsing content that's "tagged" with category keywords. They quickly provide users with a visual indication of which categories contain the most information.

Blogs and social linking networks have been quick to utilize this navigation pattern, but whether tag clouds are just the latest craze or a genuinely useful way for users to navigate content is very much a disputed topic.

In this tutorial we will be using some simple PHP and two simple tables from a MySQL database to illustrate a quick and easy method of outputting tag clouds.

Clever CSS Menus with PHP
by Gordon Mackay - 02-Aug-06
Reader Level:

In this tutorial we will explore making an intelligent CSS menu system using a very simple PHP function.

While techniques exist in CSS that allow people to add current page indication based on body tags with classes applied to them they involve the editing of the individual pages to make them function. They also do not remove the current page's link from the navigation list.

This menu will automatically remove the link from the current page navigation list item and add an ID that will allow it to be styled with a current page indicator of some sort via CSS.

Let's get started.

Full-Text Searching with MySQL and PHP - Part 2: Search Term Highlighting
by Gordon Mackay - 20-Jul-06
Reader Level:

In the last tutorial of this series I showed you how to create a FULLTEXT index in MySQL and created a query with PHP that allowed you to search through dynamic content using a simple form.

In this tutorial I will show you how to style keywords found in content so that they are highlighted for easy reading.

Google is one such search engine that highlights keywords that the user searched for in the pages generated by the search:

This is very useful as it directs the user's eyes directly to the piece of text they are searching for even when it's jumbled up among lots of other words.

In this tutorial we will create the same effect with a tiny addition to the code from the last part of the tutorial.

Making Time-Triggered Scripts
by Rob Williams - 17-Jul-06
Reader Level:

Most developers tend to think of server-side languages as user-driven applications; that is they sit dormant on a server somewhere waiting for a user to connect and make a request before actually doing anything. While this is true on many occasions, there are also times when server-side scripts need to start working without any user intervention. Unfortunately for developers who aren't entirely familiar with server environments and or are just starting out with a language this type of "non-user triggering" is fairly confusing and difficult because there aren't a lot of explanations in the server-side manuals that explain how to do it.

In this article we'll take a look at how you can acheive time-triggered (rather than user-triggered) scripting using PHP and a remote Linux server.

Full-Text Searching with MySQL and PHP
by Gordon Mackay - 13-Jul-06
Reader Level:

As a general rule of thumb, web sites that contain a large amount of content adopt some form of fuctionality that allows users to search through content held within their database.

The methods for searching database content vary from server model to server model and can often be rather complicated. However, if your web site holds its content in a MySQL database, you can very quickly add a simple but effective search mechanism using MySQL's FULLTEXT indexing.

In this tutorial we will look at using FULLTEXT indexing to create a simple content search engine that can quickly be implemented on any web site running PHP and pulling content from a MySQL database.

Making Full Use of Bindings
by Tom Muck - 31-Mar-06
Reader Level:

The Dreamweaver bindings panel has a lot of uses beyond a place to build recordsets and stored procedures. Many people don't realize that when you add session, request, and application variables to the panel manually, you get some visual advantages — the ability to drag items to the page into design view, the ability to use variables as filters, and the ability to add formatting functions to design view.

This article will explore the bindings panel and its advantages. Because we are discussing core Dreamweaver functionality, the article will apply equally to all server models in Dreamweaver, although some server models have better bindings panel support than others.

In this article we'll look at how easy it is to implement this functionality using a PHP/JavaScript solution called Speller Pages.

Speeding up AJAX with JSON
by Joel Martinez - 13-Mar-06
Reader Level:

XML is a brilliant tool for standardizing communication between two isolated systems. When you as a web developer have control over the way that both of those systems function though the benefits of XML quickly begin to fall short of the timing delays that it incurs. This is especially true of AJAX applications where you have control over both the client-side and server-side code, and thus usually don't need to waste the user's time by converting everything to XML and then back again for each transaction.

In this article we'll explore a more compact, and possibly more effective, approach to transferring complex data between two systems using JSON.

For most web developers AJAX is simply another one of those "buzz words" that represents a "revolutionary new technology" that will change the way web sites work forever. It all sounds fantastic and there are lots of great articles that explain what AJAX is and why you'd want to use it. The biggest problem for most developers is figuring out just how AJAX can be applied to real-world situations.

In this article we're going to try and tackle the implementation question. We'll take an existing PHP contact form and gradually convert it into an AJAX-driven solution. The goal is to demonstrate not only the technology and how it can be used, but also the process that you, as a developer, can take to begin the transition from traditional web development to AJAX-based pages and sites.

Running PHP under ASP.NET?? Free!
by Joel Martinez - 16-Jan-06
Reader Level:

I won't lie, I am a Microsoft lover. Their technology has been paying my salary for just about my entire career, and C# totally rocks in my quite humble opinion. But that being said, any programmer worth their salt knows that a specific technology is nothing more than a tool. If a given situation could be solved more efficiently with the use of non-Microsoft technology, then its your responsibility to investigate and (potentially) use said technology.

This article is going to review a nifty little project called Phalanger. Installing this on your ASP.NET web server allows you to deploy PHP code, even full applications like phpBB. Behind the scenes, the PHP code will be compiled to .NET code and run as an ASP.NET application.

The best thing about it is that you can, from PHP script, access .NET code (in your language of choice), and vice-versa. So if you have a nifty function written in PHP, you can use it in your .NET application. The Developers tout impressive performance improvements over the native PHP environement so this makes Phalanger an attractive target for your application platform.

A Gentle Introduction to SimpleXML
by Gordon Mackay - 12-Dec-05
Reader Level:

Once upon a time PHP developers wishing to take advantage of XML when building their applications were forced to jump through many hoops in order to parse even the most simple XML documents.

PHP 5 however has proved to be a complete rethink of the way in which PHP is able to handle simple and complex XML documents. It sports a new extension called simpleXML that allows even the most novice of PHP developers to work with XML without the urge to tear their hair from its roots.

In this tutorial we will have a look at how PHP's simpleXML could allow us to utilize XML in the real world of web development.

Preventing Form Flooding and Double Submits
by Gordon Mackay - 05-Dec-05
Reader Level:

When your sites allow users to input data via web forms it involves some risk on your part. One of those risks is flooding.

Flooding occurs when a user repeatedly inserts data in quick succession; either deliberately or by mistake. When flooding occurs by mistake it's usually because the user has either refreshed a page that still has HTTP request POST data set, or they have accidently pressed the form's submit button multiple times, the "double submit problem".

Recently many blogs have been plagued by a form of advertising that takes advantage of the ease in which a site's user can post visible content on a page. It's called "Comment Spam", and although it's almost impossible to prevent it can be limited to an extent by taking some simple measures to limit the rate in which people can send data via your forms.

In this article we will explore two methods that will ensure that you will never suffer the consequences of the double submit problem, and hopefully limit the impact of malicious user input.

Confirmation Emails

Reading Flash Metadata with PHP
by Rob Williams - 21-Nov-05

Flash 8 is the first version of the SWF file format to support standardized, native metadata. This is a great new feature that has the potential to make SWF files easier to manage, organize, and even locate through search engines. Unfortunately there's one small catch; although Flash 8 has made adding metadata to your SWF files extremely simple, at the time of writing there are very few applications/scripts/bots outside of Flash itself that actually have the ability to read that metadata!

In this article we'll take a look at a custom PHP class that can be used to read SWF metadata, and how it can be used to realize some of these great new potentials.

Using PHP to Enable Client-Side Web Services
by Rob Williams - 17-Aug-05
Reader Level:

You've just finished reading up about JavaScript's XMLHTTPRequest object when the light bulb goes on: Moving over to using XMLHTTPRequest has inadvertently forced you to deploy your own little web service! After all, if you think about it a web service is merely a remote server that you send and receive data from in a standardized format (usually XML). That's neat, but ultimately the next question arises: if a client uses XMLHTTPRequest to connect to your "web service" is it possible to use that same methodology (and code) to connect to any other public web service? If you've already gone ahead and tried this though you'll find that it's one of those "it should work but doesn't for some strange reason" problems. In this article we'll take a look at why it doesn't work quite the way you'd expect and a neat little solution to overcome the problem.

Introducing Recursive Functions in PHP Free!

CMX JumpStart: Vienna
by Sheri German - 06-Jul-05
Reader Level:

Last summer we took a trip to Germany and Austria with our son's orchestra director. My favorite city was Vienna, Austria. So it is only natural that I should choose Vienna for my city as I "change hats" from JumpStarts marketer to JumpStarts creator. I am particularly pleased and excited to offer our latest CMX JumpStart: Vienna.

In addition to the use of valid XHTML 1.0 and CSS 2.1, and in addition to validating for 508 and WAI, we have a number of special features in Vienna. This three column layout has two outer columns with fixed widths, a fluid center column for content, and fluid header and footer. There are also unordered lists for navigation: one for the main navigation, one for the sub navigation, and one for the footer navigation. We have also added a search field into an area that is at the top of the page outside the main centered layout. So far, reasonably cool, right?

But hold on. We have something far more exciting to reveal with this JumpStart. We will introduce a new and revolutionary technique called Jello Mold that has an implied minimum and maximum width that works in Internet Explorer without the use of Javascript! Furthermore, this technique allows for fluid margins on the fluid centered layout that depend on the size of the user's window.

The download folder for this article includes a bundle of 11 articles (including two about Jello Mold technique), a starter page, an images folder, four style sheets (including design-time and print), a source png, the Vienna extension, an installation and usage guide, and this article as a PDF.

PHP Site Simplification with Application.php
by Tom Muck - 15-Mar-05
Reader Level:

PHP and ColdFusion have many things in common, but they also have many differences. One of the nice features of ColdFusion that I wish I had in PHP is the Application.cfm. In the Application.cfm file, you can include things that need to be on every page, such as variables that contain connection information, often-used functions, login functionality, class instantiation, session starting, and form field cleaning, among other things. In ColdFusion, the Application.php file is automatically executed before any code on your page. To mimic this functionality in PHP, I like to create an Application.php file that I include on all my PHP pages. This article will show how an Application.php file can be used to simplify some aspects of your PHP application.

CMXMail: Creating a Generic Mail Class in PHP - Part 2
by Tom Muck - 01-Mar-05
Reader Level:

PHP has a lot of built-in functions, but for dealing with emails it is not the most friendly language, including only a generic mail() function. A way around these limitations is to use an email class to handle setting up the messages and sending them so that you don't have to create custom headers each time you use the mail() function.

Part 1 of this tutorial showed how to create a basic class. Part 2 will add to that class, and also show how to use the class in a loop, effectively creating a newsletter engine to send emails to a database.

The tutorial assumes you have set up databases and connections from PHP to MySQL.

Liverpool JumpStart with .NET
by Heidi Bautista - 31-Jan-05
Reader Level:

Ah yes, Liverpool, not only a great JumpStart, but now you can have it with ASP.NET support. In addition to a valid CSS2 and XHTML 1.0 Transitional, WAI and 508 Accessible CSS layout, you also get a dynamic ASP.NET login application. The original release of the Liverpool JumpStart comes bundled with ColdFusion, PHP, and ASP and uses Dreamweaver's built-in User Authentication Server Behaviors. Unfortunately, Dreamweaver doesn't boast similar server behaviors for ASP.NET. To help make up for that lack, here's a special tutorial just for you ASP.NET coders. I've taken the original Liverpool JumpStart pages and added the necessary ASP.NET code. The result: an out-of-the-box ASP.NET login solution combined with a versatile layout. What could be better? :-)

Included in the support files are the CF, ASP and PHP versions of the Liverpool JumpStart. There is a link at the end of the article that will allow you to download just the .NET version if you prefer, as well as a link to download the bundled tutorials that were included with the original Liverpool JumpStart.

The .NET version of Liverpool is available as a no charge upgrade to purchasers of the original Liverpool JumpStart. If you would like to receive the .NET version, please send us an email and we will send you the .NET files. Please be sure to include your name and the email address that is associated with the PayPal account used to make the purchase.

CMXMail: Creating a Generic Mail Class in PHP - Part 1
by Tom Muck - 31-Jan-05
Reader Level:

PHP has a lot of built-in functions, but for dealing with emails it is not the most friendly language, including only a generic mail() function. You have to create your own mail headers, set up separate text and HTML messages if you want to send multipart messages, and add your own attachment code. One way around this is to use an email class to handle setting up the messages and sending them so that you don't have to create custom headers each time you use the mail() function. Part 1 of this tutorial will show how to create a basic class that you can later add to.

Frequently on a dynamic page that displays a long list of content, such as a list of names, you want to allow a user to jump down to a specific letter of the alphabet. On a static list, this is easy -- just insert anchor links at key places on your page where the first letter of a word changes. On a dynamic page, it is not as easy. Using this extension, you can create a list of links for your data AND create the dynamic anchors to go along with them.

Delivering Browser Specific Styles with PHP
by Tim Green - 30-Mar-03
Reader Level:

As an agreed and recognized standard Cascading Style Sheets are an everyday part of a web developer's life. However, many developers still rely on the use of either browser trickery or client-side JavaScript to send the right stylesheet information to the right browser. While this will quite often work, newer browsers, and the ability to disable client-side Javascript means that you run the very serious risk of sending the wrong stylesheet, or even worse, no stylesheet at all. In this article we explore the use of server-side PHP code in determining which stylesheet should be presented to which browser, and all before your visitor receives anything from your website.
