Based on the code posted by gaylord dot aulke at 100days.de
i wrote this one. This should implement this function in all versions equal or greater than PHP 4.0
function array_intersect_key($arr1, $arr2) {
$res = array();
foreach($arr1 as $key=>$value) {
$push = true;
for ($i = 1; $i < func_num_args(); $i++) {
$actArray = func_get_arg($i);
if (gettype($actArray) != 'array') return false;
if (!array_key_exists($key, $actArray)) $push = false;
}
if ($push) $res[$key] = $arr1[$key];
}
return $res;
}
