PHP获取响应时间和http状态代码相同的请求

Question

I can get the HTTP status code of a URL using Curl and I can get the response time of a URL by doing something like the following...

<?php
// check responsetime for a webbserver
function pingDomain($domain){

    $starttime = microtime(true);

    // supress error messages with @
    $file      = @fsockopen($domain, 80, $errno, $errstr, 10);
    $stoptime  = microtime(true);
    $status    = 0;

        if (!$file){
            $status = -1;  // Site is down
        } else {
            fclose($file);
            $status = ($stoptime - $starttime) * 1000;
            $status = floor($status);
        }

    return $status;
}
?>

However, I'm struggling to think of a way to get the HTTP status code and the response time using the same request. If this is possible to do only via curl that would be great.

Note: I don't want/need any other information from the URL as this will slow down my process.

Please use get_headers() function it will return you status code, refer php docs - http://php.net/manual/en/function.get-headers.php

<?php 

$url = "http://www.example.com";
$header = get_headers($url);
print_r($header);
$status_code = $header[0];
echo $status_code;
?>

Output -->
