In Web programming, Personal Home Page (PHP) is a script
language and interpreter, similar to JavaScript and
Microsoft's VBScript, that
is freely available and used primarily on Linux
Web servers. PHP
(the initials come from the earliest version of the program, which was called "Personal Home Page
Tools") is a cross-platform alternative to Microsoft's Active Server Page (ASP) technology (which
runs only on Microsoft's Windows NT
servers). 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" ".php3," 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.
