for php version 5 2 17   DIR   will not work it will only works with php 5 3   But for older version of php  dirname   FILE    perfectly  For example write like this   require once dirname   FILE        db config php

In my case it doesn t work  even with   DIR   or getcwd   it keeps picking the wrong path  I solved by defining a costant in every file I need with the absolute base path of the project   if  defined  THISBASEPATH     define  THISBASEPATH     mypath       require once THISBASEPATH  cache crud php     every other require once you need     I have MAMP with php 5 4 10 and my folder hierarchy is basilar    q php  w php  e php  r php  cache a php  cache b php  setting a php  setting b php

Use     DIR     to get the current path of the script and this should fix your  problem   So   require once   DIR        class user php      This will prevent cases where you can run a PHP script from a different folder and therefore the relatives paths will not work   Edit  slash problem fixed
