什么是$ _ SERVER的区别['PHP_SELF']和$ _ SERVER ['SCRIPT_NAME']？ [英] What's the difference between $_SERVER['PHP_SELF'] and $_SERVER['SCRIPT_NAME']?

问题描述

我有一个PHP框架，我用 $ _ SERVER ['SCRIPT_NAME'] 优化的便携性。这样，我也不需要手动配置的路径了。

  $这个 - ＆GT; BASE_URL = str_replace函数（'的index.php'，''，'HTTP：//'.$_SERVER ['SERVER_NAME'] $ _ SERVER ['SCRIPT_NAME ']）;
 

但是我注意到 $ _ SERVER ['SCRIPT_NAME'] 和 $ _ SERVER ['PHP_SELF'] 返回完全相同的字符串。那么，有什么区别？我应该如何在它们之间选择？

解决方案

区别

  HTTP：//sandbox.php$c$c.eu/g/3e38d.php/test
 

脚本名称是文件的绝对路径。

PHP_SELF 是（后的.php 与路径一起）

这就像 $ _ SERVER ['SERVER_NAME'] 和 $ _ SERVER ['HTTP_HOST']

  HTTP：//sandbox.php$c$c.eu./g/f5093.phpHTTP：//sandbox.php$c$c.eu/g/f5093.php
 

现场一个区别

I have a php framework and I used $_SERVER['SCRIPT_NAME'] to optimize portability. That way I don't need to manually configure the path anymore.

$this->base_url = str_replace('index.php', '', 'http://'.$_SERVER['SERVER_NAME'].$_SERVER['SCRIPT_NAME']);

But I noticed that $_SERVER['SCRIPT_NAME'] and $_SERVER['PHP_SELF'] returns the exact same string. So, what's the difference? How should I choose between them?

解决方案

Difference

http://sandbox.phpcode.eu/g/3e38d.php/test

Script name is absolute path to file.

PHP_SELF is script you're currently in (along with "path" after .php)

It's like $_SERVER['SERVER_NAME'] and $_SERVER['HTTP_HOST']

http://sandbox.phpcode.eu./g/f5093.php

http://sandbox.phpcode.eu/g/f5093.php

spot one difference
