php application global settings

Question

I have read almost all question I have found on StackOverflow on this topic, but could not find a straight answer.

Here is my code:

Application class

Answer 1

Can you post some more code? just to show how are you accessing those settings.

anyway, you could create a Boostrap class. This bootstrap class will do anything necessary to have working environment for your application (thus, moving out the bootstrapping code from the application and settings, to this class).

it can also instantiate a Settings object, which should be a singleton.

in the Settings object, you can use magic methods (__call, __get) to access the different settings, like Settings::getSettings()->getConfigDirectory(). This magic method will strip the "get" word from the call and try to give a resource with the given name (in this case, a setting named "ConfigDirectory").

This is similar to what Zend Framework does in their Zend_Application, Zend_Bootstrap, and Zend_Config classes, you might want to check them out to get some ideas.

as a side note, i don't see (conceptually speaking) why an application should extend settings. An application should have some settings, but that's quite different from extending them.
