Homephp教程php手册PHP生成HTML纯静态网页程序代码

在php中有系统自带的全局变量$_SERVER,里面有很多参数,下面我来介绍获取URL完整路径程序代码有需要的朋友可参.

举例 URL : http://www.phprm.com/Test/Test.php,代码如下:

$_SERVER['SERVER_NAME']:www.phprm.com 
$_SERVER['SERVER_PORT']:80 
$_SERVER['REQUEST_URI']:/Test/Test.php

那我们把上面几句结合起来就可以实现了,URL完整路径为:

"http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] 

如果你是开了端口号,我们可以使用$_SERVER['SERVER_PORT']就好了,上面的代码修改一下即可,代码如下:

"http://".$_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].$_SERVER['REQUEST_URI'] 

大家要注意一点:

$_SERVER['PHP_SELFT']与$_SERVER['SCRIPT_NAME']和$_SERVER['REQUEST_URI']和$_SERVER['QUERY_STRING']的区别:

$_SERVER['PHP_SELF']会返回/phptour/test7.php/a=b,会返回文件名/后面的内容
$_SERVER['SCRIPT_NAME']只会返回/phptour/test.php,不会返回文件名后面的/后面的内容
http://localhost:60/phptour/test/test7.php/a=b
$_SERVER['PHP_SELF']将得到:/phptour/test/test7.php/a=b
$_SERVER['SCRIPT_NAME']将得到:/phptour/test/test7.php
$_SERVER['REQUEST_URI']将得到:/phptour/test/test7.php/a=b
$_SERVER['QUERY_STRING']将得到:''
