hi,
http://framework.zend.com/about/
"Zend Framework 2 is an open source framework for developing web applications and services using PHP 5.3+. Zend Framework 2 uses 100% object-oriented code and utilises most of the new features of PHP 5.3, namely namespaces, late static binding, lambda functions and closures."
Und dann scheint es bezüglich dessen auch weitere darauf aufbauende Quellen via Google-Suche (Zend Framework object oriented) zu geben, zB.:

"The Zend Framework: Writing Object-Oriented PHP with Ease."
