:axe: phinx-lightweight :axe: (VERY) Simple PHP Database Migrations

phinx-lightweight is a tool to manage and apply a sequence of migrations to your database. Migrations are written as PHP classes, and can execute SQL statements, compare & coalesce data, pull in constants and values from your application code, etc.

phinx-lightweight has (and will always have) the bare minimum of third-party dependencies, and can be used with any app or framework.

DO NOT USE THIS PACKAGE WITHOUT READING THIS

This is a permanent hard fork from robmorgan/phinx at v0.9.3. If you are migrating from phinx, you should be aware that we have made fundamental changes to the upstream version, notably:

• Migration classes will usually execute explicit SQL commands to modify the database. We have removed Phinx's entire database modelling layer and many schema manipulation helper functions. You can, of course, implement any helper functions that are useful for your app e.g. by using a custom base migration class.

• phinx-lightweight only supports MySQL (or MySQL compatible) databases over PDO, all other drivers have been removed.

• There is no mechanism for automatically rolling back migrations. Rolling back database migrations is hard, and often not as simple as applying the opposite statements in reverse. Rolling back also loses history and can leave the database in an unexpected state for the next migration. We enforce a roll-forwards-only strategy : if a migration does not work as expected in production you will need to write, commit, and deploy a new migration to get you from where you are now to where you want to be.

• We have removed functionality for seeding database content. Seeds should not be running in production and are (in our opinion) not the concern of a database migration tool. If you want to seed a development database, use one of the tools designed for that purpose.

See the changelog for more information on removed functionality.
