getPlayers.php

<?php
	/*
	
	This gets all the usernames and userIds of all users of a specific rank from a specific group (and exports them in json format).
	It works for the most part, but for some reason will not work with all groups.
	When trying to use this on specific groups ROBLOX will error on the first request.
	[LINE 118]
	
	For example:
	/getPlayers.php?group=18&rank=255
	works
	
	/getPlayers.php?group=1101003&rank=255
	does not work (there is an owner)
	
	I debugged forever and couldn't figure it out, only track it down to where it was happening, any help would be appreciated!
