Reduce dependencies on global objects

[Nick]

DamonW suggested cutting down the number of globals used throughout Hotaru. Most of these are global objects such as $db, $post, $current_user and $cage. Apparently using so many globals can be a security issue and is bad practice in object-oriented programming because it makes it difficult for other applications to use classes dependent on globals.

So perhaps this should be a priority for future revisions. The question is, what's the best way to go about it?

Here's where I get confused. Classes should be self-sufficient so they can be used in other applications, but in order for them to be self-sufficient, they would need to be independent of language files and utility functions, not to mention those darn globals!

I understand the idea of classes being libraries of common functions that applications can use, but how are you expected to wrap your entire program up in these classes if there's nothing to bind them together?

Perhaps I'm thinking too much?

Edit: I was thinking too much. Now I've made a start on 0.7 and have removed all the globals from the core. Just bug fixing and then will start on plugins.
