array_diffの連想配列対応バージョン

function array_diff_recursive($keys, $array1, ...$arrayn)
{
    foreach ($arrayn as $arrayi) {
        $array1 = array_udiff($array1, $arrayi, function($a, $b) use ($keys){
            foreach ($keys as $key) {
                $cmp = $a[$key] <=> $b[$key]; 
                if ($cmp) return $cmp;
            }
            return $cmp;
        });
    }

    return $array1;
}

$array1とその他いくつかの$arraynを$keysについて比較し、$array1にのみ存在する要素を返します。
