Answer 1

Ideally a multidimensional array is usually an array of arrays so i figured declare an empty array, then create key and value pairs from the db result in a separate array, finally push each array created on iteration into the outer array. you can return the outer array in case this is a separate function call. Hope that helps

$response = array();    
foreach ($res as $result) {
        $elements = array("firstname" => $result[0], "subject_name" => $result[1]);
        array_push($response, $elements);
    }
