Thought it might be easier if I just copied the proper definition.
Php is an open source language with a rapidly growing development community. Similar to JavaScript and Microsoft's VBScript. The initials come from the earliest version of the program, which was called "Personal Home Page Tools". As with ASP, the PHP script is embedded within a Web page along with its HTML. Before the page is sent to a user that has requested it, the Web server calls PHP to interpret and perform the operations called for in the PHP script. An HTML page that includes a PHP script is typically given a file name suffix of ".php" or ".phtml". Like ASP, PHP can be thought of as "dynamic HTML pages," since content will vary based on the results of interpreting the script. PHP is free and offered under an open source license.
