For many years, arrays have been used to logically store and sequence data. They have also been the point of confusion for many developers. In this article, Tuna will talk about the structure of arrays and how you can create and manipulate arrays with the PHP scripting language.Do you know the proper meaning of the word "Array"? At dictionary.com, an array is defined as "An arrangement of memory elements in one or more planes". For many decades now (since programming languages were first created), arrays have actively helped programmers properly utilize memory structure and allocation. In this article, you will learn about the fundamentals of arrays, as well as give some brief examples of arrays in PHP.

When you add an online rating system to your website, you will be able to give your users a chance to vote on your articles, tutorials, pictures or whatever you want. This gives your users a certain level of interactivity and tends to create a little more of a bond between for them with your website. In this tutorial, I will show you how to create an online rating system that is dynamic and uses PHP' if else statements and MySQL.

UML (Unified Modelling Language) is a mechanism for representing software in the form of diagrams. Essentially it allows to design our applications by drawing, and if the right tools existed, even generate code from the diagrams. In this article we’ll look at how PHP code is represented in UML terms, via use of the the UML class diagram.

This article is intended for the PHP programmer interested in avoiding some of the most common mistakes when applying PHP. The reader is expected to at least be familiar with PHP syntax, but should have a working knowledge of PHP functionality as well. One of PHP's greatest strengths happens to be one of its greatest weaknesses as well: PHP is easy to learn. Many people are attracted to the language because of this, not realizing that it's a lot tougher to learn how to do it

Learn how to use the include() function using the power of PHP. One of the most important and essential functions used in PHP is the include() function. The include() function lets you call an external file from your server, There are several key factors why it is rated much higher than SSI. Not only is it faster, but it burns much less CPU usage than SSI. You can keep the extension (*.php) and not have to rename it to some other extension (like *.shtml). You can call any type of file including other PHP, HTML, SHTML, CGI, etc using the include() or virtual() functions.

A Recursive function is just a function that calls itself. The first idea is that some part of the recursive function must have a value that is obtainable without another call to the function. If you don't have this, you run the danger of making an infinite loop, which is a function that continually calls itself forever. Realistically, the computer will run out of memory before forever occurs, or your computer will lose power, or you'll reboot the computer or kill the process, but it can still be a pain.

You didn't think you were going to slip right into PHP without going through the compiler/parser initiation process, did you? Don't worry, we have the "Coles Notes" on common newbie problems and errors. We will start with general syntax errors, move on to runtime errors and conclude with tips on the infamous logical errors and some last resort links to visit when all else fails. The end of this article features a bulleted checklist to consult in case of errors. Print it and keep it by your side for those gloomy Sunday nights before the deadline. Many have spent hours banging their heads against their monitors so why should you (it's an expensive habit). PHP automatically instantiates variables which means that you do not have to formerly declare them. A process called "autovivification". This is both a blessing and a curse. You don't have to worry about declaring every single variable at the top of your program (as you would in "C") but you do have to worry about misspelling your variable names and accidentally declaring new ones. Some languages, such as Perl, keep track of variables used only once and given the proper runtime options will warn you. Additionally Perl offers a very functional debugger. PHP development as of PHP 4.0.2 has not yet matured to this stage. A debugger was in development in previous PHP versions. It was last available in php3 CVS and is NOT available in PHP 4 - 4 CVS. The source has all references to the deugger_on function as php3 functions.

Debugging your code is a quite refined art that takes some time to snap into, but once you know where to look and what to look for, life instantly starts looking much much rosier.

Templates provide a simple means to seperate server side code from client side code in our scripts. This article looks at when template systems are useful, their shortcomings and why template engines are a bad idea.
