Configuration
When you initialize your project using the Init Command, Phinx
creates a default file in the root of your project directory. By default, this
file uses the YAML data serialization format, but you can use the --format
command line option to specify either yaml
, yml
, json
, or php
.
If a --configuration
command line option is given, Phinx will load the
specified file. Otherwise, it will attempt to find phinx.php
, phinx.json
,
phinx.yml
, or phinx.yaml
and load the first file found. See the
Commands chapter for more information.
Warning
Remember to store the configuration file outside of a publicly accessible
directory on your webserver. This file contains your database credentials
and may be accidentally served as plain text.
Note that while JSON and YAML files are parsed, the PHP file is included.
This means that:
It must return an array of configuration items.
The variable scope is local, i.e. you would need to explicitly declare
any global variables your initialization file reads or modifies.
Its standard output is suppressed.
Unlike with JSON and YAML, it is possible to omit environment connection details
and instead specify connection
which must contain an initialized PDO instance.
This is useful when you want your migrations to interact with your application
and/or share the same connection. However remember to also pass the database name
as Phinx cannot infer this from the PDO connection.
$app = require 'app/phinx.php';
$pdo = $app->getDatabase()->getPdo();
return [
'environments' => [
'default_environment' => 'development',
'development' => [
'name' => 'devdb',
'connection' => $pdo
]
]
];
Migration Paths
The first option specifies the path to your migration directory. Phinx uses
%%PHINX_CONFIG_DIR%%/db/migrations
by default.
Note
%%PHINX_CONFIG_DIR%%
is a special token and is automatically replaced
with the root directory where your phinx configuration file is stored.
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
Class namespaces may be specified by adding a key to each migration path:
paths:
migrations:
App\Module1\Migrations: application/module1/migrations
App\Module2\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.
Note
%%PHINX_CONFIG_DIR%%
is a special token and is automatically replaced
with the root directory where your configuration file is stored.
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'
Class namespaces may be specified by adding a key to each seed path:
paths:
seeds:
App\Module1\Seeds: application/module1/seeds
App\Module2\Seeds: application/module2/seeds
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:
The following settings are available for the adapters:
- adapter
The name of the adapter to use, e.g. pgsql
.
- host
The database server’s hostname (or IP address).
- port
The database server’s TCP port number.
- user
The username for the database.
- pass
The password for the database.
- name
The name of the database for this environment. For SQLite, it’s recommended to use an absolute path,
without the file extension.
- suffix
The suffix to use for the SQLite database file. Defaults to .sqlite3
.
- schema
For PostgreSQL, allows specifying the schema to use for the database. Defaults to public
.
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.
MySQL
The MySQL adapter has an unfortunate limitation in that it certain actions causes an
implicit commit regardless of transaction
state. Notably this list includes CREATE TABLE
, ALTER TABLE
, and DROP TABLE
, which are the most
common operations that Phinx will run. This means that unlike other adapters which will attempt to gracefully
rollback a transaction on a failed migration, if a migration fails for MySQL, it may leave your DB in a partially
migrated state.
SQLite
Declaring an SQLite database uses a simplified structure:
environments:
development:
adapter: sqlite
name: ./data/derby
suffix: ".db" # Defaults to ".sqlite3"
testing:
adapter: sqlite
memory: true # Setting memory to *any* value overrides name
Starting with PHP 8.1 the SQlite adapter supports cache
and mode
query parameters by using the URI scheme as long as open_basedir
is unset.
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.
SQL Server
When using the sqlsrv
adapter and connecting to a named instance you should
omit the port
setting as SQL Server will negotiate the port automatically.
Additionally, omit the charset: utf8
or change to charset: 65001
which
corresponds to UTF8 for SQL Server.
Custom Adapters
You can provide a custom adapter by registering an implementation of the Phinx\Db\Adapter\AdapterInterface
with AdapterFactory:
$name = 'fizz';
$class = 'Acme\Adapter\FizzAdapter';
AdapterFactory::instance()->registerAdapter($name, $class);
Adapters can be registered any time before $app->run() is called, which normally
called by bin/phinx.
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 $context the executing command object
*/
Feature Flags
For some breaking changes, Phinx offers a way to opt-out of new behavior. The following flags are available:
Since MySQL TIMESTAMP
fields do not support dates past 2038-01-19, you have the option to use DATETIME
field
types for fields created by the addTimestamps()
function:
feature_flags:
unsigned_primary_keys: false
These values can also be set by modifying class fields on the `Phinx\Config\FeatureFlags`
class, converting
the flag name to camelCase
, for example:
Phinx\Config\FeatureFlags::$unsignedPrimaryKeys = false;
