simple question about define a path

im very sorry to ask a very simple question, its seems im not understanding define path properly

as you can see

i put this at D:\Project Storage\wnmp\www\folder\scriptfolder 
example D:\Project Storage\wnmp\www\folder
define('SAMPLE1', realpath(dirname(__FILE__).'/..'));
example D:\Project Storage\wnmp\www\somefolder
define('SAMPLE2', realpath(dirname(__FILE__).'/../somefolder/'));
how  do we put like D:\Project Storage\wnmp\www\folder\scriptfo开发者_Python百科lder/ ? ( add '/') ?
define('SAMPE3', realpath(dirname(__FILE__).'/')); it seems its not working.

thanks for looking in

realpath() will never add a trailing slash because it's not a part of the path.

Either add it outside the realpath statement

realpath(dirname(__FILE__)).'/'

or when you use it

$path = ROOT."/xyz.php";
