如果要获取标题,请将选项CURLOPT_HEADER设置为1,并从curl_exec()返回的HTTP响应将包含标题.你可以解析他们的位置.

$ch = curl_init($url);
curl_setopt($ch,CURLOPT_HEADER,1); // return HTTP headers wITh response
curl_setopt($ch,CURLOPT_RETURNtransfer,1); // return the response rather than output it

$resp = curl_exec($ch);

list($headers,$response) = explode("\r\n\r\n",$resp,2);
// $headers Now has a string of the HTTP headers
// $response is the body of the HTTP response

$headers = explode("\n",$headers);
foreach($headers as $header) {
    if (strIPOs($header,'Location:') !== false) {
        echo "The location header is: '$header'";
    }
}

查看curl_setopt()的所有选项.
