Convert multidimensional stdClass object(s) to array.

objectToArray.php

<?php

    /**
     * Convert multidimensional stdClass object(s) to array
     * 
     * @param $object
     * @return array
     */
    private function objectToArray($object) {
        if (is_object($object)) {
            $object = get_object_vars($object);
        }
        if (is_array($object)) {
            return array_map(array($this, 'objectToArray'), $object);
        } else {
            return $object;
        }
    }

You would receive the same result if you encode your object(s) to json and decode it.

$array = json_decode(json_encode($object), true);
var_dump($array);
