I have a PHP file at my server root.. index.php .. which include\'s .. DIR/main.php
Now .. DIR/main.php .. has relati
Assuming main.php is a mix of HTML and PHP then when you output a link you'll need to include a prefix:
relative link
Where $web_root is your root path ('DIR'). Probably a good idea to define it in a separate include file so you only have to define it once for all your scripts.
