I just need a way to CONVERT a string(absolute path) to a 4-digit unique number
with INT!!! That's all i want!! But i cannot make it work :(
And the best part is that "that" number must be able to turn back into a path.
This way i DON'T EVEN HAVE TO STORE THE ACTUAL HTML PAGE'S ABSOLUTE PATH!!!!
1. User requests a specific html page( .htaccess gives my script the absolute
path for that .html page)
2. I turn the path into a 4-digitnumber
3. i store that number to the database. I DONT EVEN HAVE TO STORE THE PATH TO
THE DATABASE ANYMORE!!! this is just great!
I had prepared a detailed response, showing what your choices are with
this new constraint. But I can see from this post here that there's no
point, so I've thrown it out.
Either you're trolling, or you have a very limited knowledge of
mathematics. This isn't a programming problem, it's a simple problem
of information theory.
Unless you constrain your users to very restrictive filenames, what you
ask here simply cannot be done.
Perpetual motion machine, anyone? Or a compression algorithm which can
be applied repeatedly to a chunk of data until it shrinks down to one
byte? No way to do it without cheating, and the literature is full of
examples of people cheating.
