Hi, I'm using File::Find to look for files, but File::Find appears to traverse to folders in reverse aphabetical order, that is always starting from the last directory up to the first. I could of course put everything in an array and reverse it, but I could then be loading an huge array in...

Hi, I have an application that can callup any URL, including of course PHP, but only using the GET method. It's a bit unfortunate, since the users can see all the arguments passed to the script and could eventually attempt to hack it. My idee would be to have the php script check is the passed...
