只需设置选项:

CURLOPT_HEADER, 0岁 CURLOPT_RETURNTRANSFER, 1

并使用curl_getinfo与CURLINFO_HTTP_CODE(或没有opt参数，你将有一个与所有你想要的信息的关联数组)

更多信息请访问:http://php.net/manual/fr/function.curl-getinfo.php

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);

$parts = explode("\r\n\r\nHTTP/", $response);
$parts = (count($parts) > 1 ? 'HTTP/' : '').array_pop($parts);
list($headers, $body) = explode("\r\n\r\n", $parts, 2);

适用于HTTP/1.1 100在其他报头之前继续。

如果你需要使用错误服务器，只发送LF而不是CRLF作为换行符，你可以使用preg_split，如下所示:

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);

$parts = preg_split("@\r?\n\r?\nHTTP/@u", $response);
$parts = (count($parts) > 1 ? 'HTTP/' : '').array_pop($parts);
list($headers, $body) = preg_split("@\r?\n\r?\n@u", $parts, 2);

杰弗里回答的改进:

我不能得到正确的长度头部与$headerSize = curl_getinfo($this->curlHandler, CURLINFO_HEADER_SIZE);-我必须计算头部大小我自己。

此外，为了提高可读性，还做了一些改进。

$headerSize = 0;
curl_setopt_array($this->curlHandler, [
CURLOPT_URL => $yourUrl,
CURLOPT_POST => 0,
CURLOPT_RETURNTRANSFER => 1,
// this function is called by curl for each header received
CURLOPT_HEADERFUNCTION =>
         function ($curl, $header) use (&$headers, &$headerSize) {
              $lenghtCurrentLine = strlen($header);
              $headerSize += $lenghtCurrentLine;
              $header = explode(':', $header, 2);
              if (count($header) > 1) { // store only vadid headers
                   $headers[strtolower(trim($header[0]))][] = trim($header[1]);
              }
              return $lenghtCurrentLine;
           },
]);
$fullResult = curl_exec($this->curlHandler);
$result = substr($fullResult, $headerSize);

Curl有一个内置的选项，叫做CURLOPT_HEADERFUNCTION。此选项的值必须为回调函数的名称。Curl将逐行将标题(而且仅是标题!)传递给这个回调函数(因此该函数将对每个标题行调用，从标题部分的顶部开始)。然后你的回调函数可以对它做任何事情(并且必须返回给定行的字节数)。下面是经过测试的工作代码:

function HandleHeaderLine( $curl, $header_line ) {
    echo "<br>YEAH: ".$header_line; // or do whatever
    return strlen($header_line);
}


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.google.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADERFUNCTION, "HandleHeaderLine");
$body = curl_exec($ch); 

上面的工作与一切，不同的协议和代理，你不需要担心头部的大小，或设置许多不同的卷曲选项。

注:要用object方法处理标题行，请这样做:

curl_setopt($ch, CURLOPT_HEADERFUNCTION, array($object, 'methodName'))

返回带有引用参数的响应头:

<?php
$data=array('device_token'=>'5641c5b10751c49c07ceb4',
            'content'=>'测试测试test'
           );
$rtn=curl_to_host('POST', 'http://test.com/send_by_device_token', array(), $data, $resp_headers);
echo $rtn;
var_export($resp_headers);

function curl_to_host($method, $url, $headers, $data, &$resp_headers)
         {$ch=curl_init($url);
          curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $GLOBALS['POST_TO_HOST.LINE_TIMEOUT']?$GLOBALS['POST_TO_HOST.LINE_TIMEOUT']:5);
          curl_setopt($ch, CURLOPT_TIMEOUT, $GLOBALS['POST_TO_HOST.TOTAL_TIMEOUT']?$GLOBALS['POST_TO_HOST.TOTAL_TIMEOUT']:20);
          curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
          curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
          curl_setopt($ch, CURLOPT_HEADER, 1);

          if ($method=='POST')
             {curl_setopt($ch, CURLOPT_POST, true);
              curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
             }
          foreach ($headers as $k=>$v)
                  {$headers[$k]=str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', $k)))).': '.$v;
                  }
          curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
          $rtn=curl_exec($ch);
          curl_close($ch);

          $rtn=explode("\r\n\r\nHTTP/", $rtn, 2);    //to deal with "HTTP/1.1 100 Continue\r\n\r\nHTTP/1.1 200 OK...\r\n\r\n..." header
          $rtn=(count($rtn)>1 ? 'HTTP/' : '').array_pop($rtn);
          list($str_resp_headers, $rtn)=explode("\r\n\r\n", $rtn, 2);

          $str_resp_headers=explode("\r\n", $str_resp_headers);
          array_shift($str_resp_headers);    //get rid of "HTTP/1.1 200 OK"
          $resp_headers=array();
          foreach ($str_resp_headers as $k=>$v)
                  {$v=explode(': ', $v, 2);
                   $resp_headers[$v[0]]=$v[1];
                  }

          return $rtn;
         }
?>

以防你不能/不使用CURLOPT_HEADERFUNCTION或其他解决方案;

$nextCheck = function($body) {
    return ($body && strpos($body, 'HTTP/') === 0);
};

[$headers, $body] = explode("\r\n\r\n", $result, 2);
if ($nextCheck($body)) {
    do {
        [$headers, $body] = explode("\r\n\r\n", $body, 2);
    } while ($nextCheck($body));
}
