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.

Check out http://docs.phinx.org for the comprehensive documentation.

• Write database migrations using database agnostic PHP code.
• Migrate up and down.
• Migrate on deployment.
• Get going in less than 5 minutes.
• Stop worrying about the state of your database.
• Take advantage of SCM features such as branching.

• Write log files. The screen is better.
• Try to do too much. Migrations only.
• Have unreadable source code. We aim to be transparent.
• Rely on a framework. Phinx is independent. Use it with any app.
• Support anything other than MySQL. Feel free to fork and contribute if you desire.

The fastest way to install Phinx in your project is using Composer (http://getcomposer.org/).

1. Install Composer:

   curl -s https://getcomposer.org/installer | php
   

2. Add Phinx as a dependency to your composer.json file:

   {
       "require": {
           "robmorgan/phinx": "*"
       }
   }

3. Install Phinx:

   php composer.phar install
   

4. Execute Phinx:

   php vendor/bin/phinx
   

You can also use the Box application to build Phinx as a Phar archive (http://box-project.org/).

1. Clone Phinx from GitHub

   git clone git://github.com/robmorgan/phinx.git
   cd phinx
   

2. Install Composer

   curl -s https://getcomposer.org/installer | php
   

3. Install the Phinx dependencies

   php composer.phar install
   

4. Install Box:

   curl -s http://box-project.org/installer.php | php
   

5. Create a Phar archive

   php box.phar build
   

Start by forking Phinx on GitHub: https://github.com/robmorgan/phinx

Next setup your environment for development:

• curl -s https://getcomposer.org/installer | php
• php composer.phar install --dev
