.PHP2 File Extension
What is a PHP2 file?
A PHP2 file is a web file that may contain PHP 2 source code. The PHP code within the page is parsed by a PHP engine on the web server that dynamically generates HTML sent to the user's web browser. The file may be used in combination with the MySQL database.
PHP2 pages can be processed by Apache, Windows Server, or Mac OS X Server with the PHP engine installed. They can be edited with a text editor or web development program.
NOTE: The PHP2 file is uncommon since PHP pages generally use the .PHP file extension.
