How to rollback the latest Laravel database migration(s)

Ralph J. Smit Laravel & PHP-developer.

Building Laravel database migrations that are good right away is hard – especially for beginners. That’s why you’d often want to make a change to your migration, only to discover that you’ve already migrated your database. Luckily, it’s very easy in Laravel to correctly rollback only your last database migration(s).

First, let’s just check which database migrations we’ve already run. To do so, run the command php artisan migration:status on the command line (make sure to navigate to the directory with your application files first). This would give you an output like this:

php artisan migrate:status
+------+------------------------------------------------+-------+
| Ran? | Migration | Batch |
+------+------------------------------------------------+-------+
| Yes | 2014_10_12_000000_create_users_table | 1 |
| Yes | 2014_10_12_100000_create_password_resets_table | 1 |
| Yes | 2019_08_19_000000_create_failed_jobs_table | 1 |
+------+------------------------------------------------+-------+

My `php artisan migrate` gives a fatal error

Sometimes this happens, and in most cases it can be solved by running sudo composer dump-autoload before doing your migration. Also, check out the part about this command below.

How to rollback your latest Laravel database migration

In order to rollback the latest migration, you need the following command:

php artisan migrate:rollback --step=1

The command itself is very simple, but let me just explain it shortly:

  • The php artisan command specifies that you want to use Laravel's built-in command line tool, called Artisan. This tool allows you to run commands specifically for your Laravel application. Most likely you've encountered this already before.
  • The part with migrate:rollback is the actual command. It says that you want to rollback certain database migrations.
  • The last part, --step=1, is a parameter for the migrate:rollback command. By default, php artisan migrate:rollback will rollback all of your database migrations. By specifying --step=1, you're saying that you only want to rollback the latest database migration.
    Plus, if you change the number, e.g. into --step=2, you're telling Laravel to only rollback the last two migrations.

Cleaning up after rolling back a database migration

After rolling back a database migration, it's good practice to run the following command:

composer dump-autoload

This command cleans up your composer autoload file, possibly preventing errors and problems in the future.
