In Laravel, database migrations are a way to manage changes to the database schema over time. Here are some steps to handle database migrations and schema changes in Laravel:

1. Create a Migration: To create a new migration, use the `make:migration` Artisan command. This command generates a new PHP file in the `database/migrations` directory, which contains a `up` method to define the changes to be made to the database.

2. Define Schema Changes: In the `up` method of the migration file, you can define the changes to be made to the database schema using the Laravel Schema Builder. For example, you can add a new column, create a new table, or modify an existing table.

3. Run Migrations: Once you've defined your schema changes, you can run the migrations using the `migrate` Artisan command. This command will apply all pending migrations to the database.

4. Rollback Migrations: If you need to revert a migration, you can use the `migrate:rollback` Artisan command. This command will roll back the most recent migration batch.

5. Make Schema Changes: If you need to modify a migration file after it has been applied to the database, you can use the `migrate:rollback` command to revert the changes, and then modify the migration file as needed. Once you've made the changes, you can run the migrations again using the `migrate` command.

6. Seed Data: If you need to populate your database with initial data, you can use Laravel's database seeding feature. Seeders allow you to insert test data into your database quickly and easily.

Overall, handling database migrations and schema changes in Laravel is a straightforward process. By using the built-in migration features and following best practices, you can manage database changes effectively and ensure that your application's database schema stays up to date.
