Bulk Add domains to Uptime Robot's Free Plan

add-to-uptime-robot.php

<?php 
/* 
	This will add a bulk amount of domains to Uptimee Robot,
	did this due to having a massive new amount of clients 
	and wanting to streamline the pricess
	
	The function was built with the help of AI, I've corrected some stuff and added some workarounds for time limits and etc.
	
	Tested to be working, needed a couple of runs to prevent duplicate domains from being added again
	
	Hope it helps

Pro tip: Test this with one domain to make sure it's doing what you want before you fill the array with 10s of entries :)
