This tutorial introduces some of the basic programming skills required if you are going to try and learn to use PHP. We will go over a little about what PHP is and talk about some of the basic styles of programming.
Please understand that this tutorial is part of a series, and may change somewhat in the future, as it is a work in progress. The author trusts that it will be valuable and informative in your learning experience.
This elementary tutorial describes how to search an array to see if a specific item lies in it. In the tutorial, we create an array of strings such as "Apple" and "Orange" then show you how to use PHP to find out that "Apple" is in the array but "Monkey" is not. This can be useful in PHP programs if you have a collection of items (perhaps that a user has entered) and you want to know if a certain item is in that collection.
This tutorial will take you through both the IF and the IF-Else statement by comparing numbers, although relativly simple you can expand on them so that you can run checks on various things, such as passwords.
Testing your PHP Enviroment with phpinfo(). This will show you lots of useful data including a large amount of information about the current state of PHP. This includes information about PHP compilation options and extensions, the PHP version, server information and environment (if compiled as a module), the PHP environment, OS version information, paths, master and local values of configuration options, HTTP headers, and the PHP License.
