I cannot figure a way to retrieve the return statement in PHP. It works just perfect in MySQL, but this from PHP doesn't for some reason.

PHP Code:

<?php
        public function call()
        {
          $out = array();
            echo '<pre>';

            if ($this->multi_query("CALL testOut(@outvar); SELECT @outvar;"))
            {
                do
                {
                    if ($result = $this->store_result())
                    {
                        while ($row = $result->fetch_object())
                        {
                            $out[] = $row;
                        }

                        $result->close();
                    }

                    $this->next_result();
                }
                while ($this->more_results());
            }

            var_dump($out);

            return (array) $out;
        }
?>

Your return statement is mixed up. It is currently this

return (array) $out;

Try using this statement

return $out;
