<?php

namespace App\Providers;

use Illuminate\Pagination\Paginator;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        //
    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        Model::ShouldBeStrict();
        Paginator::useBootstrapFive();

        // For sub-folder migration files
        $migrationsPath = database_path('migrations');
        $paths = $this->getAllMigrationFilesIncludingTheSubFolders($migrationsPath);
        $this->loadMigrationsFrom($paths);
    }

    /**
     * getAllMigrationFilesIncludingTheSubFolders
     *
     * @param  string $directory
     * @return array
     */
    function getAllMigrationFilesIncludingTheSubFolders(string $directory): array
    {
        $directories = [];
        $folders = array_diff(scandir($directory), ['.', '..']);

        foreach ($folders as $folder) {
            $path = $directory . DIRECTORY_SEPARATOR . $folder;
            if (is_dir($path)) {
                $directories[] = $path;
                $directories = array_merge($directories, $this->getAllMigrationFilesIncludingTheSubFolders($path));
            }
        }

        return $directories;
    }
}

In order for this to work, you need to run php artisan make:migration --path=/database/migrations/your-sub-folder-name

Then run php artisan migrate
