    public function geturl($url){                $ip = "{rand(1, 255)}.{rand(1, 255)}.{rand(1, 255)}.{rand(1, 255)}";                // 初始化一个 cURL 对象        $curl = curl_init();        curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/$ip Safari/536.11");        curl_setopt($curl, CURLOPT_HTTPHEADER, array("X-FORWARDED-FOR:$ip", 'CLIENT-IP:'.$ip.''));        //curl_setopt($curl, CURLOPT_REFERER, "127.0.0.1");        // 设置你需要抓取的URL        curl_setopt($curl, CURLOPT_URL, $url);        // 设置header        curl_setopt($curl, CURLOPT_HEADER, 1);        // 设置cURL 参数,要求结果保存到字符串中还是输出到屏幕上。        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);        // 运行cURL,请求网页        $data = curl_exec($curl);        // 关闭URL请求        curl_close($curl);        return $data;    }

以上设置可以防止普通的防采集功能,效果挺明显的
