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);

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);

这里的许多答案的问题是“\r\n\r\n”可以合法地出现在html的主体中，因此您不能确保正确地分割了头文件。

在调用curl_exec时单独存储标头的唯一方法似乎是使用回调，就像上面https://stackoverflow.com/a/25118032/3326494中建议的那样

然后，为了(可靠地)获得请求的主体，您需要将Content-Length报头的值作为负起始值传递给substr()。

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);

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;
        
    }
}

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));
}
