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.
