The PHP info page, also known as the phpinfo.php file is a file that you can install on your website to show you information about PHP, and many of the options available on your webserver. It is extremely useful for webmasters, programmers and developers when installing PHP.

The file also serves as a means to show that PHP has been installed successfully and that all the requirements for the project have been met. More information about phpinfo is available at the PHP manual.
