PHP项目中的根路径变量

Question

I created a php project like this:

• img
• js
• php
  • config
    • config.php
  • pages
    • news.php
    • contact.php

I need to include my config.php into all my files news.php, contact.php

How to avoid to have a relative path like ../config/config?

I would like to have a root path like php/config/config.php.

I use MAMP Pro. Should I use an environment variable to save the root path?

Answer 1

Create a constant with absolute path to the root by using define in ShowInfo.php:

define('ROOTPATH', DIR); OR (PHP <= 5.3)

define('ROOTPATH', dirname(FILE));
