  • php 获取远程服务器信息 get_headers 的使用

    get_headers取得服务器响应一个 HTTP 请求所发送的所有标头

    $url = 'http://www.girdear.cn';
    print_r(get_headers($url));
    print_r(get_headers($url, 1));
    

    以上例程的输出类似于:

    Array
    (
        [0] => HTTP/1.1 200 OK
        [1] => Date: Sat, 29 May 2004 12:28:13 GMT
        [2] => Server: Apache/1.3.27 (Unix)  (Red-Hat/Linux)
        [3] => Last-Modified: Wed, 08 Jan 2003 23:11:55 GMT
        [4] => ETag: "3f80f-1b6-3e1cb03b"
        [5] => Accept-Ranges: bytes
        [6] => Content-Length: 438
        [7] => Connection: close
        [8] => Content-Type: text/html
    )
    
    Array
    (
        [0] => HTTP/1.1 200 OK
        [Date] => Sat, 29 May 2004 12:28:14 GMT
        [Server] => Apache/1.3.27 (Unix)  (Red-Hat/Linux)
        [Last-Modified] => Wed, 08 Jan 2003 23:11:55 GMT
        [ETag] => "3f80f-1b6-3e1cb03b"
        [Accept-Ranges] => bytes
        [Content-Length] => 438
        [Connection] => close
        [Content-Type] => text/html
    )
