A PHP object server for business logic

I wonder if such a thing is possible or eve开发者_如何学Cn exist :

In the MVC pattern, I would like to have the Model part to be persistant in memory, instead of reloading my instances at each execution. So I want only the Controller and View part to be executed.

Is there any solution of server that would provide PHP objects (just like a Mysql server provides data records), and that keeps these objects in memory ?

A problem would be also : how to have a constructed query to get objects ? Maybe PHP Linq ?

Take a look at APC and XCache. They enable you to keep any variable in memory between requests.

I found that the best solution would be to use an ORM solution like Doctrine, it handles cache in memory and all I need.
