Shared Object

I would like to open a discussion about this question: "which is the best solution for creating shared objects" I am working on a PHP framework which should speed up the development of web applications. Each section of the application is managed by a different object but most of the objects rely on a set of common facilities (DB object, Log object, etc.). At the moment, in order to share the common objects, I use this approach: all the objects are created by one single .php script following these steps: - create all the shared services - create any other object that needs access to the shared object and pass it reference to the shared services I would like to enhance this mechanism and meet the following requirements: - the mechanism should be scalable (i.e., including a new service should be straightforward) - the implementation code in the client objects should be readable (e.g., $this->DbObject->query($query);) - each service should be persistent If anybody has used the same architecture, I would like to learn about different approaches because I am not very much satisfied with my solution.
