Installation

Using Composer

composer require fyre/migration

In PHP:

use Fyre\Migration\MigrationRunner;

Basic Usage

• $container is a Container.
• $loader is a Loader.
• $connectionManager is a ConnectionManager.
• $forgeRegistry is a ForgeRegistry.

$runner = new MigrationRunner($container, $loader, $connectionManager, $forgeRegistry);

Autoloading

It is recommended to bind the MigrationRunner to the Container as a singleton.

$container->singleton(MigrationRunner::class);

Any dependencies will be injected automatically when loading from the Container.

$runner = $container->use(MigrationRunner::class);
