How can the path to the PHP interpreter be specified when setting up cron jobs in PHP scripts?

When setting up cron jobs for PHP scripts, the path to the PHP interpreter must be specified to ensure the script runs correctly. This is often necessary because cron jobs do not have access to the same environment variables as when running scripts from the command line or a web server. To specify the path to the PHP interpreter, you can use the `shebang` line at the beginning of your PHP script, which tells the system where to find the PHP executable.

#!/usr/bin/php
<?php
// Your PHP script code here
?>
