programmers, I greet
you all. I'm new to programming and I was asked to create a system that generates 14
digits pin codes at random together with their unique
serial numbers. The system
will make sure that thesame
pin is not generated twice.
The idea is to create pin
numbers for customers when the customer purchases the
pin and redeems it, that pin
can never be used again. Am
using php and mysql. Please help me, tell me where to start.
