Wanted a nice and simple PHP class which could generate random codes. After looking at multiple libraries I found that sometimes it's best done yourself.

The final class can either generate a single code or an array of codes based on the parameters you set.

Example
Generates 8 character long string

(new CodeGenerator)->generate(8);
// output: 4CF9O7XP

Show some support!
