Installation

You have two options, you can either use composer to install doctrine migrations or you can use the standalone Phar package.

Composer

Install it with composer:

$ composer require doctrine/migrations

PHP Binary / PHAR

You can download the Migrations PHP Binary, which is a standalone PHAR package file with all the required dependencies. You can drop that single file onto any server and start using the Doctrine Migrations.

To register a system command for the migrations you can create a simple batch script, for example on a \*nix Environment creating a `/usr/local/bin/doctrine-migrations`:

#!/bin/sh
php /path/to/doctrine-migrations.phar "[email protected]"

You could now go and use the migrations like:

[shell]
myshell> doctrine-migrations

Because the PHAR file is standalone it does not rely on the Symfony Console 'db' Helper, but you have to pass a `--db-configuration` parameter that points to a PHP file which returns the parameters for `Doctrine\DBAL\DriverManager::getConnection($dbParams)`. If you don't specify this option Doctrine Migrations will look for a `migrations-db.php` file returning that parameters in your current directory and only throw an error if that is not found.

Configuration

The last thing you need to do is to configure your migrations. You can do so by using the --configuration option to manually specify the path to a configuration file. If you don't specify any configuration file the tasks will look for a file named migrations.xml or migrations.yml at the root of your command line. For the upcoming examples you can use a migrations.xml file like the following:

1<?xml version="1.0" encoding="UTF-8"?> <doctrine-migrations xmlns="http://doctrine-project.org/schemas/migrations/configuration" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/migrations/configuration http://doctrine-project.org/schemas/migrations/configuration.xsd"> <name>Doctrine Sandbox Migrations</name> <migrations-namespace>DoctrineMigrations</migrations-namespace> <table name="doctrine_migration_versions" /> <migrations-directory>/path/to/migrations/classes/DoctrineMigrations</migrations-directory> </doctrine-migrations>

Of course you could do the same thing with a configuration.yml file:

1name: Doctrine Sandbox Migrations migrations_namespace: DoctrineMigrations table_name: doctrine_migration_versions migrations_directory: /path/to/migrations/classes/DoctrineMigrations

With the above example, the migrations tool will search the migrations_directory recursively for files that begin with Version followed one to 255 characters and a .php suffix. Version.{1,255}\.php is the regular expression that's used.

Everything after Version will be treated as the actual version in the database. Take the file name VersionSomeVersion.php, SomeVersion would be the version number stored in the migrations database table. Since versions are ordered, doctrine generates version numbers with a date time like Version20150505120000.php. This ensures that the migrations are executed in the correct order.

While you can use custom filenames, it's probably a good idea to the Doctrine generate migration files for you.

And if you want to specify each migration manually in YAML you can:

1table_name: doctrine_migration_versions migrations_directory: /path/to/migrations/classes/DoctrineMigrations migrations: migration1: version: 20100704000000 class: DoctrineMigrations\NewMigration

If you specify your own migration classes (like `DoctrineMigrations\NewMigration` in the previous example) you will need an autoloader unless all those classes begin with the prefix Version*, for example path/to/migrations/classes/VersionNewMigration.php.
