Hello everyone, What is the best way to generate unique activation keys that look like xxxx-xxxx-xxxx-xxxx where x is a hexdecimal number so for example 53e1-fbaf-4230-6c7a. I thought I could use.
Generates a random password drawn from the defined set of characters.
- In other words, first 8 hex chars = Unixtime, last 5 hex chars = microseconds. This is why it has microsecond precision. Also, it provides a means by which to reverse-engineer the time when a uniqid was generated: date('r',hexdec(substr(uniqid,0,8))).
- Hi, I was wondering how I could randomly generate a string of 8 characters (letters and numbers) down a column and have each row unique. What I'm trying to do is assign a random 8 character password to a few hundred user names in a new column beside the user name.

- Php artisan make:migration createuserstable The new migration will be placed in your database/migrations directory. Each migration file name contains a timestamp, which allows Laravel to determine the order of the migrations.
