如何正确链接文件？

Question

From my previous experience, I've almost always had problems with linking files with my website projects.

For example, linking CSS styles, Javascript files and including files in PHP. The problem is, that on my PC, the directory of my project was /www/project-name/ and when I put the project on a server, the directory would be just /www/. When I uploaded the project to a server, images wouldn't show, styles wouldn't work, database connections wasn't set, functions were not defined etc...

So my question is: What is the best and most efficient way to link/include files?

Something that will work no matter what the directory of the project is, and possibly, if I include project/includes/mysql.class.php in file1.php, and I move that file to a different directory, it would still properly include project/includes/mysql.class.php

You should use relative paths.

Instead of specifying the full path ('/www/project-name/includes/whatever.php'), use a path relative to the current location:

'./includes/whatever.php'
