How can I define the DIRECTORY_SEPARATOR for both Windows and Linux platforms?

Question

Now I create a small PHP Application, here I have problem for using file path, because in Windows use this type location C:\Some\Location\index but in Linux /www/app/index so when I define the path using this / but when the application run in window machine it should be problem for this /.

So here I want to define the DIRECTORY_SEPARATOR both Windows and Linux platform.

Answer 1

PHP accepts both \ and / as valid path separators in all OS. So just use / in your code

Answer 2

For convenience you can write define a shorter constant:

DEFINE('DS', DIRECTORY_SEPARATOR);  

and then write your path as:

$path = 'www'.DS.'app'.DS.'index';  

Or do I not understand your question?
