[PHP-DB] Re: please help.. serial number generator From: JJ Harrison (webmaster <email protected>)
Date: 07/30/02

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() is often used to store passwords and make them non-viewable.

if you are just looking for a unique number an auto-increment coloumn in
mysql or what ever should do it.
