//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);
