答
如果禁用了get_headers，那么你也可以使用cURL。
If get_headers is disabled then you can also use cURL instead.
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => $url,
CURLOPT_HEADER => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_NOBODY => true));
$header = explode("\n", curl_exec($curl));
curl_close($curl);
print_r($header);
