$request = $this->get('request');

$request->isXmlHttpRequest(); // Ajax のリクエストかどうか？

$request->getPreferredLanguage(array('en', 'fr'));

$request->query->get('page'); // $_GET のパラメータを取得

$request->request->get('page'); // $_POST のパラメータを取得

オブジェクトを配列へ変換

function object_to_array($obj) {
      $_arr = is_object($obj) ? get_object_vars($obj) : $obj;
      foreach ($_arr as $key => $val) {
              $val = (is_array($val) || is_object($val)) ? object_to_array($val) : $val;
              $arr[$key] = $val;
      }
      return $arr;
  }

その２

    function _object_to_array($object) {
        $new = NULL;
        if( is_object($object) ){
            $object=(array)$object;
        }
        if( is_array($object) ){
            $new = array();
            foreach( $object as $key => $val ){
                $key = preg_replace("/^\\0(.*)\\0/","",$key);
                $new[$key] = $this->_object_to_array($val);
            }
        }
        else{
            $new = $object;
        }
        return $new;
    }
