Learn PHP

PHP is a server side scripting language. This means that programmes in PHP are included in amongst the normal text of HTML pages and that these programs are executed by a PHP enabled WWW server. The output from the programs is included in the HTML page text as a replacement for the original PHP programme.

PHP is most commonly associated with the Apache WWW server and is almost certainly the most widely used scripting language on the WWW. The commonest current version is PHP 4, but PHP 5 is widely available.

By using PHP we can interact with database servers and manage the page content accordingly. The difference between a static page like HTML and dynamic page like PHP is the way the server interpret the request.
