I have a PHP file at my server root.. index.php .. which include
's .. DIR/main.php
Now .. DIR/main.php .. has relative links to many nearby files.
All the relative links are broken.
Any way I can change the relative-URL base path for links?
... so the included content of DIR/main.php has all its links to friend1.php changed to DIR/friend1.php.
Edit: This in NOT about include's, this is about CHANGING ahref links en-masse.
The base tag in html works for relative links. See w3schools for an example on how to use it.
Assuming main.php is a mix of HTML and PHP then when you output a link you'll need to include a prefix:
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.
The picture isn't too clear but you can probably rearrange a few files and use symlinks to solve the problem.
For your example, you could make a symlink DIR/friend1.php that points to /friend1.php, but you would have to do this for all your files, or just move them.
