How can the PHP integration with Apache be checked to ensure proper functionality?

To ensure proper functionality of PHP integration with Apache, you can check the PHP configuration file (php.ini) to make sure it is properly configured to work with Apache. Additionally, you can create a PHP file with the phpinfo() function to view the PHP configuration settings in a web browser. This will help you verify that PHP is properly integrated with Apache and running correctly.

<?php
phpinfo();
?>
