Fatal error: Call to undefined function: array_intersect_key()...

Thats because this function is from PHP 5.1.0 and up.
You can create your own function and place it into the module.

Example:

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;
}

It worked! Thanks, docc!

This is a duplicate of #247217.
