Php 使用curl获取请求和响应头

我使用以下代码获取了标题响应

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, 1);
$c = curl_exec('http://plagiarismcheckerx.com');
echo $c;
curl_close($ch);

但我得到的只是回应标题。但另一个区段请求标头未接收

我得到了以下回应

但实际和完整的标题如下所示。我从网络部分的chrome开发者工具中复制了它

如何获得与chrome结果类似的完整标题详细信息？有一个解决方案的可能重复项是curl_setopt（$ch，CURLOPT_header，1）；curl_setopt（$ch，CURLINFO_HEADER_OUT，true）$数据=curl_exec（$ch）；var_dump（$数据）；变量转储（curl_getinfo（$ch））；这也不起作用$curl-v-I-H如何用php编写
