Models and database access


Models provide a representation of data in the MVC application. There is no Zend\Model component that is provided by Zend Framework, so developers have to decide on the implementation part of models. Models by themselves cannot talk to databases and fetch or process data, so they are usually connected to mapper objects or use ORM to connect to databases. For this example, we will be using a TableGateway pattern for storing data in the database.

Note

TableGateway is a built-in Zend Framework 2 DB pattern which acts as a gateway to a database table, having access to all table rows for performing various SQL operations including select, insert, update, and delete.

TableGateway

The TableGateway pattern is used for creating an object that represents a table in the database; in this example, we will need a TableGateway object for the User table.

Tip

The exchangeArray() method needs to be declared in the model if the model uses TableGateway for database storage.
