DZone.com: PHP objects in MongoDB with Doctrine

On DZone.com today Giorgio Sironi has a new post showing how you can use Doctrine with MongoDB to work with Document objects from the database.

In the PHP world, probably the Doctrine ODM for MongoDB is the most successful. This followes to the opularity of Mongo, which is a transitional product between SQL and NoSQL, still based on some relational concepts like queries. [...] The case for an ODM over a plain Mongo connection object is easy to make: you will still be able to use objects with proper encapsulation (like private fields and associations) and behavior (many methods) instead of extracting just a JSON package from your database.

He briefly mentions that the PECL extension for Mongo needs to be installed prior to trying out any of the examples. His first example shows how to create a DocumentManager (similar to the normal EntityManager for those familiar with Doctrine). He also shows an integration with the ORM and shares some of the findings he's made when it comes to versioning the resources (hint: annotations are your friend).
