How can PHP scripts be modified to enforce CLI execution instead of relying on IP address checks for access control?

To enforce CLI execution instead of relying on IP address checks for access control in PHP scripts, you can use the `php_sapi_name()` function to check if the script is being run from the command line interface. This method is more secure and reliable than relying on IP address checks. 

if (php_sapi_name() !== 'cli') {
    die("This script can only be executed from the command line interface.");
}
