How can the lack of availability of $_SERVER variable affect PHP scripts when run as Cronjobs?

When PHP scripts are run as Cronjobs, the $_SERVER variable is not always available because it is a part of the web server environment. This can cause issues if the script relies on values from $_SERVER, such as HTTP headers or server information. To solve this issue, you can manually set the necessary values in the script or pass them as arguments when calling the script from the command line. 

// Set necessary values if $_SERVER is not available
if (!isset($_SERVER['SERVER_NAME'])) {
    $_SERVER['SERVER_NAME'] = 'localhost';
}

// Use the value of SERVER_NAME in the script
$serverName = $_SERVER['SERVER_NAME'];
echo "Server Name: $serverName";
