I want to make a registration form that ensure registers enter their email address, then the system auto generates a 8-digit random number and send this number to the email.

The problem are:

1. how to generate the random number
2. how to send this number to the email
3. how to store both email and the number into SQL or a simple text file.

Thanks.
