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);

如果你正在使用GET，试试这个:

$curl = curl_init($url);

curl_setopt_array($curl, array(
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "GET",
    CURLOPT_HTTPHEADER => array(
        "Cache-Control: no-cache"
    ),
));

$response = curl_exec($curl);
curl_close($curl);

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));
}

更好的方法是使用详细的CURL响应，可以通过管道连接到临时流。然后可以在响应中搜索报头名称。这可能需要一些调整，但对我来说很管用:

class genericCURL {
    /**
     * NB this is designed for getting data, or for posting JSON data
     */
    public function request($url, $method = 'GET', $data = array()) {
        $ch = curl_init();
        
        if($method == 'POST') {
            
            curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
            curl_setopt($ch, CURLOPT_POSTFIELDS, $string = json_encode($data));
            
        }

        
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_VERBOSE, true);
        
        //open a temporary stream to output the curl log, which would normally got to STDERR
        $err = fopen("php://temp", "w+");
        curl_setopt($ch, CURLOPT_STDERR, $err);
        

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        $server_output = curl_exec ($ch);
        
        //rewind the temp stream and put it into a string   
        rewind($err);
        $this->curl_log = stream_get_contents($err);
        
        curl_close($ch);
        fclose($err);

    
        return $server_output;
        
    }
    
    /**
     * use the curl log to get a header value
     */
    public function getReturnHeaderValue($header) {
        $log = explode("\n", str_replace("\r\n", "\n", $this->curl_log));
        foreach($log as $line) {
            //is the requested header there
            if(stripos($line, '< ' . $header . ':') !== false) {
                $value = trim(substr($line, strlen($header) + 3));
                return $value;
            }
        }
        //still here implies not found so return false
        return false;
        
    }
}

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;
         }
?>

如果你不需要使用curl;

$body = file_get_contents('http://example.com');
var_export($http_response_header);
var_export($body);

的输出
