How can one ensure that their computer is running when a CronJob needs to be executed?

To ensure that a CronJob is executed when needed, one can create a script that checks if the computer is running at the scheduled time and if not, wakes it up. This can be achieved by using a wake-on-LAN (WoL) command to wake the computer from sleep mode before the CronJob is supposed to run. 

<?php
// Set the MAC address of the computer to wake up
$macAddress = '00:11:22:33:44:55';

// Execute wake-on-LAN command to wake up the computer
exec('wakeonlan ' . $macAddress);
?>
