Description:
------------
array_diff_uassoc bug..

this function is diff args[0] to args[n-1]   
* args[n] == "user function" 



if (args[0].value == args[n-1].value) 
   ==> run to "user function" 

but..

PHP Version 5.3.5-1ubuntu7.7 

not run...






Test script:
---------------
function key_compare_func($key1, $key2)
{
    echo $key1. " ". $key2 . "<br>";

    if ($key1 == $key2)
        return 0;
    else if ($key1 > $key2)
        return 1;
    else
        return -1;
}

$array1 = array('1-1' => 1, '1-2' => 2, '1-3' => 3,
'1-4' => 4);
$array2 = array('2-1' => 5, '2-2' => 6, '2-3' => 7,
'2-4' => 8);

var_dump(array_diff_uassoc2($array1, $array2, 'key_compare_func'));


Expected result:
----------------
function php_compat_array_diff_uassoc()

{

    $args = func_get_args();
    if (count($args) < 3) {
        user_error('Wrong parameter count for array_diff_uassoc()', E_USER_WARNING);
        return;
    }
    $compare_func = array_pop($args);
    if (!is_callable($compare_func)) {
        if (is_array($compare_func)) {
            $compare_func = $compare_func[0] . '::' . $compare_func[1];
        }
        user_error('array_diff_uassoc() Not a valid callback ' .


            $compare_func, E_USER_WARNING);

        return;

    }

    $array_count = count($args);
    for ($i = 0; $i !== $array_count; $i++) {
        if (!is_array($args[$i])) {
            user_error('array_diff_uassoc() Argument #' .
                ($i + 1) . ' is not an array', E_USER_WARNING);
            return;
        }
    }
    $result = array();
    foreach ($args[0] as $k => $v) {
        for ($i = 1; $i < $array_count; $i++) {
            foreach ($args[$i] as $kk => $vv) {
                if ($v == $vv) {
                    $compare = call_user_func_array($compare_func, array($k, $kk));
                    if ($compare == 0) {
                        continue 3;
                    }
                }
            }

        }

        $result[$k] = $v;
    }
    return $result;
}
