I'm currently connecting to a remote host in PHP CLI and sending some headers. My script then waits for the response. I can have it all print out, but then it returns the HTML. I only want the headers. How can I do this?

推荐答案

接收HTTP响应的格式与发送请求基本相同:headers和body用两个CRLF( ).

The format for receiving a HTTP response is basically the same as for sending a request: headers and body are separated with two CRLF ( ).

$parts = explode("

", $http_response);
$headers = array_shift($parts);
$body = implode("

", $parts);
