One of the great benefits of making this an application component is that from now on we can reference the database connection simply as a property of the main Yii application Yii app - db anywhere throughout our application. Similarly we can do this for any of the components defined in the config file. All of our examples will be using the MySQL database. However we will be providing the low-level DDL statements for the table structures and we will try to keep things generic from a database implementation perspective. It is entirely possible to follow along using any Yii-compatible database of your choice. At the time of writing Yii has Active Record support for MySQL PostgresSQL SQLite SQL Server and Oracle. The charset property set to utf8 sets the character set used for database connection. This property is only used for MySQL and PostgreSQL databases. We are setting it here to ensure proper utf8 unicode character support for our PHP application. The emulatePrepare true configuration sets a PDO attribute PDO ATTR_EMULATE_PREPARES to true which is recommended if you are using PHP or higher. So we have specified a MySQL database called trackstar_dev as well as the username and password needed to connect to this database. We did not show you how to create such a database in MySQL. We assume you have a favorite database you are going to use as you follow along and know how to create a new database. Please refer to your specific database documentation if you are unsure of how to create a new database called trackstar_dev and define a username and password for connectivity. Once the database is in place we can test it again by running our unit test again phpunit unit PHPUnit by Sebastian Bergmann.
