如何使用 PHP 或 JavaScript 获取客户端响应标头？

Question

guys. I'm building a crypto coin mining pool, the original pool was based off of Node.JS. Which Node.JS is not up to the fast pace of the mining pool. So I was building the pool to run in NGINX and PHP. How the miner works, it interacts with the pool API. The miner has some important information in headers, such as miner type, version, capacity, and etc. Is there a way to get the headers with PHP preferably, if not can it be done with JavaScript. Thanks. :)

With Node.JS I was using: req.headers

This is what I have tried in PHP:

$_SERVER["USER"] = www-data
$_SERVER["HOME"] = /var/www
$_SERVER["HTTP_HOST"] = 10.10.31.95
$_SERVER["HTTP_USER_AGENT"] = Jetty/9.4.2.v20170220
$_SERVER["HTTP_ACCEPT_ENCODING"] = gzip
$_SERVER["REDIRECT_STATUS"] = 200
$_SERVER["SERVER_NAME"] = _
$_SERVER["SERVER_PORT"] = 80
$_SERVER["SERVER_ADDR"] = 10.10.31.95
$_SERVER["REMOTE_PORT"] = 57488
$_SERVER["REMOTE_ADDR"] = 10.10.30.0
$_SERVER["SERVER_SOFTWARE"] = nginx/1.10.3
$_SERVER["GATEWAY_INTERFACE"] = CGI/1.1
$_SERVER["REQUEST_SCHEME"] = http
$_SERVER["SERVER_PROTOCOL"] = HTTP/1.1
$_SERVER["DOCUMENT_ROOT"] = /var/www/html
$_SERVER["DOCUMENT_URI"] = /burst.php
$_SERVER["REQUEST_URI"] = /burst?requestType=getMiningInfo
$_SERVER["SCRIPT_NAME"] = /burst.php
$_SERVER["CONTENT_LENGTH"] = 
$_SERVER["CONTENT_TYPE"] = 
$_SERVER["REQUEST_METHOD"] = GET
$_SERVER["QUERY_STRING"] = requestType=getMiningInfo
$_SERVER["SCRIPT_FILENAME"] = /var/www/html/burst.php
$_SERVER["PATH_INFO"] = 
$_SERVER["FCGI_ROLE"] = RESPONDER
$_SERVER["PHP_SELF"] = 
$_SERVER["REQUEST_TIME_FLOAT"] = 1507362021.8898
$_SERVER["REQUEST_TIME"] = 1507362021

This works

function get_contents() {
  file_get_contents("http://example.com");
  var_dump($http_response_header);
}
get_contents();
var_dump($http_response_header);

Out put.

array(13) {
[0]=> string(15) "HTTP/1.0 200 OK" 
[1]=> string(20) "Accept-Ranges: bytes" 
[2]=> string(29) "Cache-Control: max-age=604800"
