I need to create some kind of 10 digits serial number where I can generate
and check that it is valid. Sort of like a checksum..
How many unique values do you need, and how hard-to-fake?
I
if u are looking for a simple random string try this php:
echo md5(time());
or md5() a random number your choice.
md5() genetates a one way non-reversable hash. which could be kept in a db.
here is an example of the md5 hash of my library card number:
11d560821fb027c227d837df53a5a73a
md5()

use the MD5 function and just take the 1st 10 chars or better yet, once you have
the MD5 value, use a wacky routine to take the first 10 odd position values...
since each time you run the function, it will always return the same value
(given the same string parameter...).
