PHP Write bulk generate non-duplicated card number password code

This article to share is a very practical code, the project often need to use, you can batch generation of the card number of the password 2 methods, the need for small partners to refer to it.

When the pain of the egg, by the way to strengthen their own in the PHP array manipulation of some skills, wrote the following a small code, you can randomly generate the corresponding array of card number password, and automatically to repeat, the idea is not, purely nonsense.
