What are the necessary server requirements, such as PHP and MySQL support, for building a custom CMS in PHP?

When building a custom CMS in PHP, it is essential to ensure that your server meets the necessary requirements. This includes having support for PHP (at least version 7.0) and MySQL (or another database system) to store and retrieve content and user data. Additionally, having access to a web server, such as Apache or Nginx, is necessary to host and serve your PHP files to visitors. 

<?php
// Check PHP version
if (version_compare(PHP_VERSION, '7.0', '<')) {
    die('Your server must have PHP version 7.0 or higher to run the CMS.');
}

// Check MySQL support
if (!extension_loaded('mysqli')) {
    die('Your server must have MySQL support (mysqli extension) to run the CMS.');
}

// Additional server requirements can be checked here

// Your CMS code goes here
?>
