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);

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

我的方法是

$response = curl_exec($ch);
$x = explode("\r\n\r\n", $v, 3);
$header=http_parse_headers($x[0]);
if ($header=['Response Code']==100){ //use the other "header"
    $header=http_parse_headers($x[1]);
    $body=$x[2];
}else{
    $body=$x[1];
}

如果需要，应用for循环并移除爆炸限制。

如果你特别想要Content-Type，有一个特殊的cURL选项来检索它:

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
$content_type = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);

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);

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;
        
    }
}
