Question

How can I validate the multidimensional array.My array is like

Array
(
    [level] => Array
        (
            [1] => 1
            [2] => 2
        )

    [subject] => Array
        (
            [1] => Array
                (
                    [0] => 4
                    [1] => 9
                )

            [2] => Array
                (
                    [0] => 4
                )

If I understood:

array_diff_key($myArray['level']), $myArray['subject']);

sample: http://codepad.org/i00KNhDJ

Order is important:

array_diff_key($myArray['level']), $myArray['subject']) !== array_diff_key($myArray['subject']), $myArray['level']);

Use array_diff_key?

if (count(array_intersect_key($array['level'], $array['subject'])) !=
    count($array['level'])) {
    echo 'level and subject have different keys';
}
