PHP/MySQL - Best way to create unique random string?

Question

How do I create a random unique string in MySQL?

when I need to create a random string in PHP I use this function:

public function generateString($le         


        

Answer 1

Why not just use the built-in functions for generating unique identifiers? You wouldn't have to worry about duplicates that way.

Both PHP and MySQL have their own.

PHP: uniqid()

MySQL: UUID()
