-------------

[](#configuration)

The main section of the config.

- **default\_connection** - *The default connection alias to use if none specified.*
- **connections** - *A collection of database connection alias names and connection specific config.*

The connections sections are grouped with the database connection being aliased as the config key name and requires the following.

- **env** - *The connection environment.*
- **dsn** - *The connection data source name to connect to.*
- **database** - *The database name the connection is for.*
- **username** - *The database username to use for the connection.*
- **password** - *The password to use in conjunction with the username.*
- **port** - *Optional database connection port number, defaults to 3306.*
- **use\_mamp\_sockets** - *Optional flag to indicate the MAMP socket config should be added to the PDO connection.*

#### Example YAML Config Content

[](#example-yaml-config-content)

```
default_connection: main
connections:
    main:
        env: local
        dsn: localhost
        database: database
        username: username
        password: password
        port: 3306
        use_mamp_sockets: false

```

ToDo

- **Connection** - *Log SQL failure and check if it is a MySQL Server has gone away error and needs to reconnect in query().*
- **Connection** - *Add the DB aliases for the connection and PDO connections attributes in \_\_toString().*
