What steps should be taken to ensure PHP is correctly installed on a web server?

To ensure PHP is correctly installed on a web server, you should check if the PHP module is installed and enabled in the server configuration. You can also create a PHP file with the phpinfo() function to check the PHP version and configuration settings. Additionally, make sure that PHP scripts are being executed properly by the server. 

<?php
// Check if PHP is installed and enabled
if (function_exists('phpinfo')) {
    phpinfo();
} else {
    echo 'PHP is not installed or enabled on this server.';
}
?>
