Question

If I should point to a directory from everywhere in the site which is the best procedure?

$folder = "http://www.mysite.com/something/foldertopoint"

or

$folder = "/WEB/mysite/htdocs/something/foldertopoint"

Answer 1

Why not use something like __DIR__ it is a magical constant. If you define a path in say a config file

Path to config file: /var/www/include/config.php

inside you have say

define('_INC_', __DIR__);

Anywhere you use the constant _INC_ will always point to /var/www/include

so if you are in: /var/www/some/crazy/path/of/nonsense.php

You can simply use

include(_INC_."/myinclude.php");

which will include /var/www/include/myinclude.php

saves time when trying to include folers/files site-wide.
