Re: Find Resource Overlaps in an Array

I think I figured out the first function:

function check_for_overlap($array, $resource, $sourceStart, $sourceEnd, $KeyResource, $tKeyStart, $tKeyEnd){
	$out = array();
	if(is_array($array)){
		foreach ($array as $r){
			if ($r[$KeyResource] == $resource){
				if($sourceStart < $r[$tKeyEnd] && $sourceEnd > $r[$tKeyStart]){
					$out[] = $r;
				}
			}
		}	
	}
	if(count($out) > 0) return true;
}

I would appreciate if someone one would confirm that this will work or if there is a more efficient way to handle this. Thanks!

No to move to the next function.
