Phinx

Most database migration tools are framework-dependent, complicated, confusing to install/configure and a pain in the ass to write migrations for. In less than 5 minutes you can install Phinx, create and execute your first migration. Phinx supports migrations written in both PHP and SQL. Use the PHP syntax to make your migrations portable between different database vendors or hand-code advanced queries. It's your choice. As Phinx executes from the command-line, it is painless to integrate with your deploy, build or CI tool. Phinx is and will always remain completely free, open-source software. Developers are encouraged to fork, hack and modify Phinx. Phinx makes it ridiculously easy to manage the database migrations for your PHP app. In less than 5 minutes, you can install Phinx and create your first database migration. Phinx is just about migrations without all the bloat of a database ORM system or framework.
