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));
}

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;
         }
?>

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

以下是我对这场辩论的看法……这将返回一个单独的数组，其中分隔了数据并列出了标题。这是基于CURL将返回一个头数据块[空行]数据

curl_setopt($ch, CURLOPT_HEADER, 1); // we need this to get headers back
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, true);

// $output contains the output string
$output = curl_exec($ch);

$lines = explode("\n",$output);

$out = array();
$headers = true;

foreach ($lines as $l){
    $l = trim($l);

    if ($headers && !empty($l)){
        if (strpos($l,'HTTP') !== false){
            $p = explode(' ',$l);
            $out['Headers']['Status'] = trim($p[1]);
        } else {
            $p = explode(':',$l);
            $out['Headers'][$p[0]] = trim($p[1]);
        }
    } elseif (!empty($l)) {
        $out['Data'] = $l;
    }

    if (empty($l)){
        $headers = false;
    }
}

PHP文档注释中发布了一个解决方案:http://www.php.net/manual/en/function.curl-exec.php#80442

代码示例:

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
// ...

$response = curl_exec($ch);

// Then, after your curl_exec call:
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);

警告:正如下面的评论所指出的，当与代理服务器一起使用或在处理某些类型的重定向时，这可能不可靠。@Geoffrey的回答可能会更可靠地处理这些问题。

这就是你想要的吗?

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
$response = curl_exec($ch); 
list($header, $body) = explode("\r\n\r\n", $response, 2);
