PHP超级全局变量数组详解

这些主机头信息，在RewriteRule规则时非常有用

1，如果请求http://www.anxuexi.com/test.php?a=1&b=1&sdfsd234234234，则$_GET变量如下

Array
(
    [a] => 1
    [b] => 1
    [sdfsd234234234] => 
)

最常用的$_SERVER变量如下：
Array
(
    [HOSTNAME] => AY120722104353f9d8080
    [PATH] => /usr/local/bin:/usr/bin:/bin
    [TMP] => /tmp
    [TMPDIR] => /tmp
    [TEMP] => /tmp
    [OSTYPE] => 
    [MACHTYPE] => 
    [MALLOC_CHECK_] => 2
    [USER] => www
    [HOME] => /home/www
    [FCGI_ROLE] => RESPONDER
    [GATEWAY_INTERFACE] => CGI/1.1

    [REMOTE_PORT] => 3545
    [SERVER_ADDR] => 42.121.19.159//服务器端ip地址
    [SERVER_PORT] => 80
    [SERVER_NAME] => www.anxuexi.com

        (
            [0] => a=1&b=1&sdfsd234234234
        )

    [argc] => 1
