Configuration¶

Migration Paths¶

The first option specifies the path to your migration directory. Phinx uses %%PHINX_CONFIG_DIR%%/db/migrations by default.

In order to overwrite the default %%PHINX_CONFIG_DIR%%/db/migrations, you need to add the following to the configuration.

paths:
    migrations: /your/full/path

You can also provide multiple migration paths by using an array in your configuration:

paths:
    migrations:
        - application/module1/migrations
        - application/module2/migrations

You can also use the %%PHINX_CONFIG_DIR%% token in your path.

paths:
    migrations: '%%PHINX_CONFIG_DIR%%/your/relative/path'

Migrations are captured with glob, so you can define a pattern for multiple directories.

paths:
    migrations: '%%PHINX_CONFIG_DIR%%/module/*/{data,scripts}/migrations'

Custom Migration Base¶

By default all migrations will extend from Phinx’s AbstractMigration class. This can be set to a custom class that extends from AbstractMigration by setting migration_base_class in your config:

migration_base_class: MyMagicalMigration

Seed Paths¶

The second option specifies the path to your seed directory. Phinx uses %%PHINX_CONFIG_DIR%%/db/seeds by default.

In order to overwrite the default %%PHINX_CONFIG_DIR%%/db/seeds, you need to add the following to the yaml configuration.

paths:
    seeds: /your/full/path

You can also provide multiple seed paths by using an array in your configuration:

paths:
    seeds:
        - /your/full/path1
        - /your/full/path2

You can also use the %%PHINX_CONFIG_DIR%% token in your path.

paths:
    seeds: '%%PHINX_CONFIG_DIR%%/your/relative/path'

Custom Seeder Base¶

By default all seeders will extend from Phinx’s AbstractSeed class. This can be set to a custom class that extends from AbstractSeed by setting seed_base_class in your config:

seed_base_class: MyMagicalSeeder

Custom Migration Template¶

Custom template for Migrations could be used either by defining template file path in configuration file:

templates:
    file: src/templates/customMigrationTemplate.php

Custom Seeder Template¶

Custom Seeder template could be used either by defining template file path in configuration file:

templates:
    seedFile: src/templates/customSeederTemplate.php

Environments¶

One of the key features of Phinx is support for multiple database environments. You can use Phinx to create migrations on your development environment, then run the same migrations on your production environment. Environments are specified under the environments nested collection. For example:

environments:
    default_migration_table: phinxlog
    default_environment: development
    production:
        adapter: mysql
        host: localhost
        name: production_db
        user: root
        pass: ''
        port: 3306
        charset: utf8mb4
        collation: utf8mb4_unicode_ci

would define a new environment called production.

In a situation when multiple developers work on the same project and each has a different environment (e.g. a convention such as <environment type>-<developer name>-<machine name>), or when you need to have separate environments for separate purposes (branches, testing, etc) use environment variable PHINX_ENVIRONMENT to override the default environment in the yaml file:

export PHINX_ENVIRONMENT=dev-`whoami`-`hostname`

Migration Table¶

To keep track of the migration statuses for an environment, phinx creates a table to store this information. You can customize where this table is created by configuring default_migration_table to be used as default for all environments:

environment:
    default_migration_table: phinxlog

If this field is omitted, then it will default to phinxlog. For databases that support it, e.g. Postgres, the schema name can be prefixed with a period separator (.). For example, phinx.log will create the table log in the phinx schema instead of phinxlog in the public (default) schema.

You may also specify the migration_table on a per environment basis. Any environment that does not have a migration_table specified will fallback to using the default_migration_table that is defined at the top level. An example of how you might use this is as follows:

environment:
    default_migration_table: phinxlog
    development:
        migration_table: phinxlog_dev
        # rest of the development settings
    production:
        # rest of the production settings

In the above example, development will look to the phinxlog_dev table for migration statues while production will use phinxlog.

Table Prefix and Suffix¶

You can define a table prefix and table suffix:

environments:
    development:
        ....
        table_prefix: dev_
        table_suffix: _v1
    testing:
        ....
        table_prefix: test_
        table_suffix: _v2

Socket Connections¶

When using the MySQL adapter, it is also possible to use sockets instead of network connections. The socket path is configured with unix_socket:

environments:
    default_migration_table: phinxlog
    default_environment: development
    production:
        adapter: mysql
        name: production_db
        user: root
        pass: ''
        unix_socket: /var/run/mysql/mysql.sock
        charset: utf8

External Variables¶

Phinx will automatically grab any environment variable prefixed with PHINX_ and make it available as a token in the config file. The token will have exactly the same name as the variable but you must access it by wrapping two %% symbols on either side. e.g: '%%PHINX_DBUSER%%'. This is especially useful if you wish to store your secret database credentials directly on the server and not in a version control system. This feature can be easily demonstrated by the following example:

environments:
    default_migration_table: phinxlog
    default_environment: development
    production:
        adapter: mysql
        host: '%%PHINX_DBHOST%%'
        name: '%%PHINX_DBNAME%%'
        user: '%%PHINX_DBUSER%%'
        pass: '%%PHINX_DBPASS%%'
        port: 3306
        charset: utf8

Data Source Names¶

Phinx supports the use of data source names (DSN) to specify the connection options, which can be useful if you use a single environment variable to hold the database credentials. PDO has a different DSN formats depending on the underlying driver, so Phinx uses a database-agnostic DSN format used by other projects (Doctrine, Rails, AMQP, PaaS, etc).

<adapter>://[<user>[:<pass>]@]<host>[:<port>]/<name>[?<additionalOptions>]

• A DSN requires at least adapter, host and name.

• You cannot specify a password without a username.

• port must be a positive integer.

• additionalOptions takes the form of a query string, and will be passed to the adapter in the options array.

environments:
    default_migration_table: phinxlog
    default_environment: development
    production:
        # Example data source name
        dsn: mysql://root@localhost:3306/mydb?charset=utf8

Once a DSN is parsed, it’s values are merged with the already existing connection options. Values in specified in a DSN will never override any value specified directly as connection options.

environments:
    default_migration_table: phinxlog
    default_environment: development
    development:
        dsn: '%%DATABASE_URL%%'
    production:
        dsn: '%%DATABASE_URL%%'
        name: production_database

If the supplied DSN is invalid, then it is completely ignored.

Supported Adapters¶

Phinx currently supports the following database adapters natively:

• MySQL: specify the mysql adapter.

• PostgreSQL: specify the pgsql adapter.

• SQLite: specify the sqlite adapter.

• SQL Server: specify the sqlsrv adapter.

For each adapter, you may configure the behavior of the underlying PDO object by setting in your config object the lowercase version of the constant name. This works for both PDO options (e.g. \PDO::ATTR_CASE would be attr_case) and adapter specific options (e.g. for MySQL you may set \PDO::MYSQL_ATTR_IGNORE_SPACE as mysql_attr_ignore_space). Please consult the PDO documentation for the allowed attributes and their values.

For example, to set the above example options:

$config = [
    "environments" => [
        "development" => [
            "adapter" => "mysql",
            # other adapter settings
            "attr_case" => \PDO::ATTR_CASE,
            "mysql_attr_ignore_space" => 1,
        ],
    ],
];

By default, the only attribute that Phinx sets is \PDO::ATTR_ERRMODE to PDO::ERRMODE_EXCEPTION. It is not recommended to override this.

environments:
    development:
        adapter: sqlite
        name: ./data/derby
        suffix: ".db"    # Defaults to ".sqlite3"
    testing:
        adapter: sqlite
        memory: true     # Setting memory to *any* value overrides name

environments:
    testing:
        adapter: sqlite
        name: my_app
        mode: memory     # Determines if the new database is opened read-only, read-write, read-write and created if it does not exist, or that the database is a pure in-memory database that never interacts with disk, respectively.
        cache: shared    # Determines if the new database is opened using shared cache mode or with a private cache.

$name  = 'fizz';
$class = 'Acme\Adapter\FizzAdapter';

AdapterFactory::instance()->registerAdapter($name, $class);

Templates¶

You may override how phinx generates the template used with in a handful of ways:

• file - path to an alternative file to use.

• class - class to use for the template, must implement the Phinx\Migration\CreationInterface interface.

• style - style to use for template, either change or up_down, defaults to change if not set.

You should only use one of these options. These can be overridden by passing command line options to the Create Command <commands. Example usage within the config file is:

templates:
    style: up_down

Aliases¶

Template creation class names can be aliased and used with the --class command line option for the Create Command.

The aliased classes will still be required to implement the Phinx\Migration\CreationInterface interface.

aliases:
    permission: \Namespace\Migrations\PermissionMigrationTemplateGenerator
    view: \Namespace\Migrations\ViewMigrationTemplateGenerator

Version Order¶

When rolling back or printing the status of migrations, Phinx orders the executed migrations according to the version_order option, which can have the following values:

• creation (the default): migrations are ordered by their creation time, which is also part of their filename.

• execution: migrations are ordered by their execution time, also known as start time.

Bootstrap Path¶

You can provide a path to a bootstrap php file that will be included before any phinx commands are run. Note that setting External Variables to modify the config will not work because the config has already been parsed by this point.

paths:
    bootstrap: 'phinx-bootstrap.php'

Within the bootstrap script, the following variables will be available:

/**
 * @var string $filename The file name as provided by the configuration
 * @var string $filePath The absolute, real path to the file
 * @var \Symfony\Component\Console\Input\InputInterface $input The executing command's input object
 * @var \Symfony\Component\Console\Output\OutputInterface $output The executing command's output object
 * @var \Phinx\Console\Command\AbstractCommand $context the executing command object
 */

Feature Flags¶

For some breaking changes, Phinx offers a way to opt-out of new behavior. The following flags are available:

• unsigned_primary_keys: Should Phinx create primary keys as unsigned integers? (default: true)

• column_null_default: Should Phinx create columns as null by default? (default: true)

feature_flags:
    unsigned_primary_keys: false

These values can also be set by modifying class fields on the `Phinx\Config\FeatureFlags` class, converting the flag name to camelCase, for example:

Phinx\Config\FeatureFlags::$unsignedPrimaryKeys = false;
