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;
}
}
?>
