For a project, I need a method of creating thousands of random strings while keeping collisions low. I'm looking for them to be only 12 characters long and uppercase only. Any suggestions?
There are many ways to generate a random, unique, alphanumeric string in PHP which are given below: Using str_shuffle() Function: The str_shuffle() function is an inbuilt function in PHP and is used to randomly shuffle all the characters of a string passed to the function as a parameter.
CODE:
from random import choice from string import ascii_uppercase print(''.join(choice(ascii_uppercase) for i in range(12)))
OUTPUT:

EDIT:
If you need only digits, use the digits
constant instead of the ascii_uppercase
one from the string
module.
