$page_url = "http://dev.kdlapi.com/testproxy";
//代理服务器
$proxy = "47.115.5.19:16816";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $page_url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
//设置代理
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//自定义header
$headers = array();
$headers[] = 'User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0);';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
//自定义cookie
curl_setopt($ch, CURLOPT_COOKIE,'');
curl_setopt($ch, CURLOPT_ENCODING, 'gzip'); //使用gzip压缩传输数据让访问更快
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
echo $result;
echo "\n\nfetch ".$info['url']."\ntimeuse: ".$info['total_time']."s\n\n";
