Kindly solve this issue!!!!

meta.php on line 43 starts with " array_push "

function get_des_templates($type)
{
    global $wpdb;
    $q = "SELECT * from ".$wpdb->prefix."options WHERE option_name LIKE 'des_template_[$type]_%'";
    $res = $wpdb->get_results($q, ARRAY_A);
    $output = array();
    foreach($res as $r)
    {
        $options = unserialize(trim($r['option_value']));
        if (is_string($options))
        {
            $options = unserialize($options);
        }
        array_push($output, array("id"=>$options['des_template_tab']['name'], "name"=>$options['des_template_tab']['nicename']));
    }
    return $output;
}
