Web applications read and persist data to a database. In Symfony, this can be done by using PDO or a custom framework. Many developers are using Doctrine, as Symfony provides good integration for it. The Symfony Plugin provides several code completion and navigation facilities for Doctrine.

Retrieve a specific repository by means the Doctrine's object manager.
Call the methods of a specific repository.
Call the methods of a specific entity fetched from the repository.
Create queries on the object/relational model with Doctrine QueryBuilder.
Specify the fields to search by when calling such functions as
Code navigation for entities and fields
To navigate to the declaration of an entity, position the caret at its usage and press Ctrl+B. Alternatively, Ctrl+Click the usage. If both the entity and the repository declarations are located, choose a specific declaration to navigate to from the popup menu.
Navigating to declaration is available for fields, too.
