ecmall源码中的 function _config_view()-关于重写

   function assign($k, $v = null)
    {
        $this->_init_view();
        if (is_array($k))
        {
            $args  = func_get_args();
            foreach ($args as $arg)     //遍历参数
            {
                foreach ($arg as $key => $value)    //遍历数据并传给视图
                {
                    $this->_view->assign($key, $value);
                }
            }
        }
        else
        {
            $this->_view->assign($k, $v);
        }
    }


  function _init_view()
    {
        
        if ($this->_view === null)
        {
            $this->_view =& v();
            $this->_config_view();//配置     
        } 
    }


 function _config_view()
    {
  
        echo  ‘1234567890‘;
    }
