postgresqlHow can I integrate PostgreSQL with Yii2?

PostgreSQL can be integrated with Yii2 by using the PostgreSQL Extension for Yii2. This extension provides a PostgreSQL database driver and schema migration tool for Yii2 applications. To use the extension, first install it using Composer:

composer require yiisoft/yii2-postgres

Once the extension is installed, you can configure the database connection in the application configuration file:

'components' => [
    'db' => [
        'class' => 'yii\db\Connection',
        'dsn' => 'pgsql:host=localhost;dbname=mydatabase',
        'username' => 'myuser',
        'password' => 'mypassword',
    // ...

  • yiisoft/yii2-postgres - The PostgreSQL Extension for Yii2.
  • yii\db\Connection - The class that represents the database connection.
  • pgsql:host=localhost;dbname=mydatabase - The DSN (Data Source Name) used to connect to the database.
