Introduction and Installation of PHP

What is PHP?

PHP is an acronym for Hypertext Preprocessor. It is a dynamic server side scripting language that allows an application developer to create very simple to very complex mechanisms for the web. Think of PHP as the brain and central nervous system behind your applications. PHP code can be directly mingled in with your HTML page content as long as the page has a .php extension ( myPage.php ). Or it can be scripts and class files placed on server and connected to your front-end files. Any HTML file you have can be turned into a PHP file and PHP script will run inside it.

PHP’s syntax is very similar to ActionScript(used in Flash and Flex) and JavaScript. So when someone learns any one of these three languages they have a good head start when it comes time to learn the other two. The logic behind PHP is very easy to understand and master once you create a few applications. PHP can also work in tandem with these other languages. You can send information back and forth when needed, to process information in any way you want.

PHP Processing Requirements (installation)

You have two options to enable yourself to work with PHP.

1. Build and test on your web server (easy)

2. Most people starting in PHP development already have a web server online. Simply create your .php files, FTP them into your web directory and the server will parse them for you automatically. Most web hosts offer PHP support, and if your host does not, consider switching to a better one.

If you do not have a web server online yet, you can buy a Domain Name for about $10 and set up a free or paid hosting account for that domain name. Be sure to choose PHP and not ASP if given a choice. Then you can FTP files to the server and test online
