PHP Templating System

[frandy]

Hey,

Im learning php and learning at quite a fast rate. What im interest in getting help/guidance on is a php/mysql templating system. I already have a file based templating system but im interested in making it easier for users to edit if I had it a mysql templating system..like vBulletin.

Im also interested in how vbulletin does phrases from the database like..in a template you put something like $welcome_message and it displays "Welcome User!" or whatever.

I've tried looking at vBulletins code and database but its just too large to read/learn and understand from for me just now.

Any guidance/help is appreciated!
