I have the following file structure:
rootDIR dir1 subdir1 file0.php file1.php dir2 file2.php file3.php file4.php
file1.php requires file3.php and file4.php from dir2 like this :
require('../../dir2/file3.php') file2.php requires file1.php like this:
require('../dir1/subdir1/file1.php') But then require in file1.php fails to open file3.php and file4.php ( maybe due to the path relativeness)
However, what is the reason and what can I do for file2.php so file1.php properly require file3.php and file4.php?

The way I do it is visual. I put my mouse pointer on the index. php (looking at the file structure), then every time I go UP a folder, I type another "../" Then you have to make sure you go UP the folder structure ABOVE the folders that you want to start going DOWN into. After that, it's just normal folder hierarchy.
Relative pathsIf you don't supply the root, it means that your path is relative. The simplest example of relative path is just a file name, like index. html . So one should be careful with relative paths. If your current directory is /about/ then index.
Relative path Relative paths make use of two special symbols, a dot (.) and a double-dot (..), which translate into the current directory and the parent directory. Double dots are used for moving up in the hierarchy.
For relative paths you can use __DIR__ directly rather than dirname(__FILE__) (as long as you are using PHP 5.3.0 and above):
require(__DIR__.'/../../dir2/file3.php'); Remember to add the additional forward slash at the beginning of the path within quotes.

Try adding dirname(__FILE__) before the path, like:
require(dirname(__FILE__).'/../../dir2/file3.php'); It should include the file starting from the root directory
