parse_url类似于$_SERVER

它的用途是获取网址

相比而言，$_SRVER获取的网址的信息更多，更具体一些

下面说一下parse_url:

<?php

$Url='http://www.yidawang.net/index.html';
$tempu=parse_url($Url);
print_r($tempu);die;

打印的结果为：Array( [scheme] => http [host] => www.yidawang.net [path] => /index.html)

$message=$tempu['host'];
echo $message;

输出的结果为：www.yidawat_ng.net(域名)

而$_SERVER

echo "<pre>";

print_r($_SERVER);
