How to generate PHP enums from database in Laravel?

A magic number is a configuration parameter typed as a number in the middle of some code.

And that magic number is a bad thing.

Using this library, you will fix the following code:

How to use this generator?

First of all, install composer package:

composer require dobron/laravel-db-enum-generator

Let's say the user_roles database table has the following structure:

Id	Slug	Role
1	MANAGER	Admin
2	CONTENT_CREATOR	Editor
3	MODERATOR	Moderator
4	ADVERTISER	Advertiser
5	INSIGHTS_ANALYST	Analyst

Now call artisan command make:enum.

# with laravel model
php artisan make:enum UserRoleTypes --model=UserRole --id=Id --slug=Slug --title=Role

# with laravel model that does not have slug column (will be auto-generated from --title)
php artisan make:enum UserRoleTypes --model=UserRole --id=Id --title=Role

# with database table
php artisan make:enum UserRoleTypes --table=user_roles --id=Id --slug=Slug --title=Role

# etc.

The UserRoleTypes.php file was generated in the ./app/enums/ directory.
If you update the database table, just use the same command with the --force flag to overwrite the file.

How to find magic numbers in the project?

I recommend using a library called PHPMND.

This stands for PHP Magic Number Detector.

A detailed installation guide can be found at https://github.com/povils/phpmnd

But if you're using Composer, here's how you can install it quickly:

composer require --dev povils/phpmnd

Once that's done, you run it like this:

phpmnd .
