in_array does not work for this case:

If all items of an array as elements (not as an array) are in another array. For example:

$arr1 = array("aaa", "bbb", "ccc", "ddd");
$arr2 = array("aaa", "bbb");

The following function is a solution to work it out:
<?
function arrElement_in_array($arr2, $arr1){
	foreach($arr2 as $v){
		if(in_array($v, $arr1)){
           $count++; 
		}
	}
	//if all elements of arr2 are in arr1
	if($count==count($arr2)){
		return true;
	}
}
?>
