Relative URLS across different sub folders

Looking for a way of allowing my links and include URLs etc to work on my local machine correctly as well as on my live site.

I have for example a common.php file which contains my DB connection.

I also have a init.php file which is included on every page and inside that includes the common.php file (among others)

For now, i have used

include './common.php';

However, if i am in a page e.g. web/settings

the ./ points to the settings folder.

What should i be using as a relative URL that will work across the whole site no matter what folder etc?

the quick answer for a path is this.

__DIR__ = current working directory so If you have MVC type architecture ( single point of entry aka front controller, basically everything starts off in one file, typically index.php, and the rest are included ) you can just define a constant like this in that main file.

define( 'BASE_PATH', __DIR__.'/' );

So if you have like this

root
    index.php //define basepath
    includes :
        other.php
    template :
        temp.php

in other you can just do

include BASE_PATH . 'template/temp.php';

everything will be tied by that one base set in the main index.php file, and as long as the folder i put above as root contains everything you can move that where ever you want because of the dynamic part __DIR__

The long answer is to use a PSR-0 autoloader but that might be a bit overkill.

As a side not if you are on PHP < 5.3 use this instead of __DIR__

dirname(__FILE__)

You could use $_SERVER['DOCUMENT_ROOT'] for this. 

set_include_path( get_include_path() . PATH_SEPARATOR . $_SERVER['DOCUMENT_ROOT'] );

// Now, you can specify your path relative to your DOCUMENT_ROOT.
include('common.php'); // Assuming your common.php file is in your root path.

You'll find it alot more convenient using namespaces though, so you might want to go down that road.

How about /? It refers to the base, and from there you can use the absolute path:

include "/absolute/path/to/file/common.php";

A relative URL is always affected by the current directory, and you can't make it the same no matter where you are on the site. You need to use absolute paths.
