How can a user ensure that their web server supports PHP?

To ensure that a web server supports PHP, a user can create a PHP file with a simple phpinfo() function call and access it through a web browser. If PHP is supported, the PHP information page will be displayed showing the PHP version, configuration settings, and other details. If the page is blank or displays the PHP code instead of executing it, PHP may not be properly configured on the server. 

<?php
phpinfo();
?>
