> Guaranteed to be unique?  Not even remotely possible.  Even with a lookup table approach (which defeats your purpose of not storing the path) with 4 digits you're looking at a maximum 10000 unique file paths before your system duplicates numbers.  And that's the best-case scenario.  Anything else would be worse.

Finally!!!!!! THANK YOU VERY MUCH!!! THIS IS WHAT I WAS LOOKING FOR!!!

NOW, if you please explain it to me from the innermost parenthesis please, because i do want to understand it!!!

And since i'am sure it works, and i just used it on http://superhost.gr
please view my domain and help me understand why its producing errors for me.
Your 1-line code surely works but somethings not letting my webpage load normally.

Please take a look....
