How to store the root of my "subsite"

I need to add my "web app" to an existing site. It will be placed in a separate folder.

What is the best way to define the root for my app? It will have no interaction with the rest of the site.

I thought of just creating a .php script in my root and do something like:

define('ROOT_DIR', dirname(__FILE__));

And then include this file in all other scripts.

Is this the right way to do it?

Solution

  • FROM PHP DOC on dirname(__FILE__) or __DIR__

    Given a string containing the path of a file or directory, this function will return the parent directory's path.

    This can easily change depending on our be structure and one single config file

    eg.

    http://example.com = /public_html
http://example.com/mobile = /public_html/mobile

    My Advice .. HARD CODE it since it is always fixed 

    define('ROOT_DIR','/public_html');

    if you have a file in /public_html/class/HelloWord.class.php

    You can easy access it has the following no matter your current directory 

     ROOT_DIR . '/class/HelloWord.class.php' ;
