PHP compare array

I have to compare two arrays in php and print the out put if the both arrays are same but can order elements in any way

ie 

$array1=array('a','p','p','l','e');
$array2=array('p','a','e','l');

--- This must return as success because all of the letters in array1 is there in array2

$array1=array('a','p','p','l','e','s');
$array2=array('p','a','e','l');

-- This must return false

$array1=array('a','p','p','l','e','s');
$array1=array('a','p','p','l','e','s');
-- This must return true

Please help

function compareArrays($array1, $array2) {
    foreach ($array2 as $currentValue) {
        if (!in_array($currentValue, $array1) {
            return false;
        }
    }
    return true;
}
