获取301状态肯定没问题。
| 代码如下 | 复制代码 |
|
function getrealurl($url){ $header = get_headers($url,1); if (strpos($header[0],'301') || strpos($header[0],'302')) { if(is_array($header['Location'])) { return $header['Location'][count($header ['Location'])-1]; |
|
补充:get_headers — 取得服务器响应一个 HTTP 请求所发送的所有标头
| 代码如下 | 复制代码 |
|
$url = 'http://111cn.net'; print_r(get_headers($url)); |
|
结果
| 代码如下 | 复制代码 |
