directory_map() not working outside of application

[quote author="iamdadude" date="1274383116"]It's blank. I made sure that there's nothing else that could be throwing off a PHP error, and it still showed blank.

Here's what I have in the controller -

Code:

function create_path() {
            
            $canopen = opendir(realpath('../'));
            die($canopen);
                        
        }

If it doesn't return anything or false it means it can't open the directory.
