.php

A PHP page is a Web page that contains PHP code. When a PHP page is accessed in a Web browser, the PHP scripts are parsed by the Web server, which generates HTML. The resulting HTML is then sent to the client's Web browser, which displays the Web page. Therefore, the user never sees the PHP code, but only the HTML.

PHP pages are often used to display dynamic content and to access data from back-end data sources, such as a MySQL database. Since PHP is open-source, it is a common language used to create database-driven websites on Apache servers.
