复制代码 代码如下:


//开始缓存图片         

        ob_start();//启用输出缓存,暂时将要输出的内容缓存起来 

        imagejpeg($newimage,false,$quality);//输出 

        $data = ob_get_contents();//获取刚才获取的缓存 

        ob_end_clean();//清空缓存 

        $mem =get_memcache();//自己修改 

        $mem->set($mem_key,$data,720000);//将刚才获取的输出存到memcache里 

        echo $data;//输出图片 

      然后显示的时候这样

        $mem = get_memcache();//自己修改 
        $data = $mem->get($mem_key);

        if($data) {

            echo $data;

            exit();

        }
