relative path for file_exists

[kishan]

Hi all

i have a separate module in my app like module1

i want to have the relative path in all the files in that module

for ex libs/Atmail/Config.php was located under C:\xampp\htdocs\app\module1\submodule1\libs/Atmail/Config.php

 

but i want to use some thing like file_exists('libs/Atmail/Config.php')

 

so iam giving some thing like $path='C:\xampp\htdocs\app\module1\submodule1';

 

set_include_path(get_include_path() . PATH_SEPARATOR . $path);

 

will it work im not getting the expected result...

 

Please help
