How can global variables be utilized to avoid specifying the absolute path to the PHP executable when calling a script?

To avoid specifying the absolute path to the PHP executable when calling a script, you can set up a global variable in your PHP script that contains the path to the PHP executable. This way, you can easily reference the variable whenever you need to call the PHP executable without hardcoding the path each time. 

<?php
// Define a global variable for the path to the PHP executable
$php_path = '/usr/bin/php';

// Use the global variable when calling the PHP executable
exec($php_path . ' path_to_your_script.php');
?>
