假如你项目首页的URL是：www.test.com/other/Form

假如当前模块是：Index

假如当前操作是：index

那么首页完整的URL：http://www.test.com/other/Form/index.php/Index/index

__ROOT__：/other/thinkphp/mydemo

__SELF__：/other/thinkphp/mydemo/Form/index.php

__ACTION__： /other/thinkphp/mydemo/Form/index.php/Index/index

__URL__： /other/thinkphp/mydemo/Form/index.php/Index

__APP__： /other/thinkphp/mydemo/Form/index.php

__PUBLIC__：/other/thinkphp/mydemo/Public

../public(不区分大小写)：/other /thinkphp/mydemo/Form/Tpl/default/Public

APP_PUBLIC_URL：/other/thinkphp/mydemo/Form/Tpl/default/Public

WEB_PUBLIC_URL：/other/thinkphp/mydemo/Public

模板中对路径部分的操作是这样子的,PHP代码:

• //项目公共目录  
•    $tmplContent = str_ireplace('../public',APP_PUBLIC_URL,$tmplContent);
• //网站公共目录  
•     $tmplContent = str_replace('__PUBLIC__',WEB_PUBLIC_URL,$tmplContent);
•   //网站根目录  
•     $tmplContent = str_replace('__ROOT__',__ROOT__,$tmplContent);
•   //当前项目地址  
•     $tmplContent = str_replace('__APP__',__APP__,$tmplContent);
•    //当前模块地址  
•      $tmplContent = str_replace('__URL__',__URL__,$tmplContent);
•    //当前项目操作地址  
•     $tmplContent = str_replace('__ACTION__',__ACTION__,$tmplContent);
•     //当前页面操作地址  
• $tmplContent = str_replace('__SELF__',__SELF__,$tmplContent);
  

测试网址:http://localhost/blog/testurl.php?id=5

• //获取域名或主机地址
• echo $_SERVER['HTTP_HOST']."
• "; #localhost
• //获取网页地址
• echo $_SERVER['PHP_SELF']."
• "; #/blog/testurl.php
• //获取网址参数
• echo $_SERVER["QUERY_STRING"]."
• "; #id=5
• //获取用户代理
• echo $_SERVER['HTTP_REFERER']."
• ";
• //获取完整的url
• echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
• echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING'];
• #http://localhost/blog/testurl.php?id=5
• //包含端口号的完整url
• echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
• #http://localhost:80/blog/testurl.php?id=5
• //只取路径
• $url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"];
• echo dirname($url);
• #http://localhost/blog
