Hello all,
so im kinda stumped. Im a real big O'Riellys fan, so i came across one of tuts in PHP Cookbook. So basically i wanna display files in a folder or a directory using this code. The only problem is that when i load it in a page, it says: is not inside the document root. now i know this cause i have not specified anything in the "$dir", but even when i specify a folder, then ill get: foldername is not inside the document root. My "document root" is C:\xampp\htdocs . what could be the problem? i have tried alot.
