Question

我使用curl --interface ip_goes here -I -L https://www.youtube.com/来获取http标头，但我想将HTTP/1.1 200 OK存储在变量中。我可以用preg_match来做，但我想知道是否有更有效的解决方案

试试这个：

$str="HTTP/1.1 200 OK
Date: Fri, 09 Jan 2015 05:49:12 GMT
Server: gwiseguy/2.0
Content-Type: text/html; charset=utf-8

X-Frame-Options: SAMEORIGIN 
more string....";
    $a=explode("\n",$str);
    var_dump($a[0]);

输出： string 'HTTP/1.1 200 OK'
