How can a PHP script automatically execute another script without user intervention?

To automatically execute another PHP script without user intervention, you can use the `exec()` function in PHP to run the script from within your main script. This function allows you to execute a command as if it were typed directly into the command line. Make sure to provide the full path to the script you want to execute.

// Execute another PHP script without user intervention
exec('php /path/to/another_script.php');
