PHP Socket编程 之 fsockopen异步请求执行https(ssl)站点方法分享
1、 fsockopen
/**
* 异步 执行程序
* @param string $path 异步url 地址
* @param array $postData 传递的参数
* @param string $method 请求方式
* @param string $url 请求地址
* @return bool
*/

2、CURL
/**

* @return string|bool
*/

//检查地址是否为空
if (empty($url)) {
return false;
}
//控制请求方法范围
$httpMethod = array('GET', 'POST', 'PUT', 'DELETE');
$method = strtoupper($method);
if (!in_array($method, $httpMethod)) {
return false;
}
//请求头初始化
$request_headers = array();
$User_Agent = 'Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.43 Safari/537.31';

curl_setopt($ch, CURLOPT_TIMEOUT, 1);//设置超时时间为1秒,超过1秒则关闭连接
#curl_setopt($ch, CURLOPT_NOSIGNAL, 1); //注意，毫秒超时一定要设置这个
#curl_setopt($ch, CURLOPT_TIMEOUT_MS, 200); //超时毫秒，cURL 7.16.2中被加入。从PHP 5.2.3起可使用

curl_setopt($ch, CURLOPT_AUTOREFERER, 1); // 自动设置Referer
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//获取的信息以文件流的形式返回
curl_setopt($ch, CURLOPT_BINARYTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);//https 不进行ssl验证

注：测试发现 fsockopen 请求执行https时，有两个乱码总是：
1，返回头中 Content-Encoding: gzip 表示body是gzip压缩格式的，body需要gzdecode(body)解压
2，返回头中 Transfer-Encoding: chunked 分块传输编码
