Laravel代码生成器

Question

I am using Laravel 4 and I am looking for a system to generate simple short alphanumeric codes, kinda like what Steam does when you login from a new machine, they send you an email with some text like this:

Someone has tried to log in into your account from an unknown device. If this is really you, please input this code to authenticate the access:

ZT27K

Thank you

Is there some sort of random, short codes generator in Laravel?

Answer 1

Yup! A bit down on the helpers documentation page is the str_random() function, which can be used anywhere like so:

$string = str_random(5);

(Note: it defaults to 16 if its length argument is left out.)
