[12.x] Update the db:seed command to accept multiple seeders separated by commas

[kevinb1989]

In our large projects, I sometimes don't want to run all seeders, a single seeder, but just a sub set of seeders.

// Before
php artisan db:seed --class=GenresSeeder
php artisan db:seed --class=DirectorsSeeder
php artisan db:seed --class=MoviesSeeder

// After
php artisan db:seed --class=GenresSeeder,DirectorsSeeder,MoviesSeeder

Of course I can create another seeder and group the above together using the call function. But it would be kinda hard and clunky to name and remember that aggregating seeder. This change will make things straightforward and easier.

I have tested in local, everything works as expected:

When you would work with arrays, you could use built-in functionality:

- php artisan db:seed --class=GenresSeeder,DirectorsSeeder,MoviesSeeder
+ php artisan db:seed --class=GenresSeeder --class=DirectorsSeeder --class=MoviesSeeder

[kevinb1989]

php artisan db:seed --class=GenresSeeder --class=DirectorsSeeder --class=MoviesSeeder

@shaedrich Is that already possible running the above command? Still, I find it weird calling the class option multiple times in one command.

That's how normal commands work 🤷🏻‍♂️ We shouldn't reinvent the wheel. Laravel can deal with arrays. No custom string splitting needed.

Thanks for your pull request to Laravel!

Unfortunately, I'm going to delay merging this code for now. To preserve our ability to adequately maintain the framework, we need to be very careful regarding the amount of code we include.

If applicable, please consider releasing your code as a package so that the community can still take advantage of your contributions!

No problem.
