How to manage templates in most effective way

[impact]

Hello,

I am trying to create multiple templates in my site so that user can choose different look and feel depending up on their personal preferences but the problem is, in my script there are too many "include_once". I am wondering if this is going to effect the performance in any way. Here are the steps to my templates..

1. the index file load (include_once) template file after fetching template preference data from database.

2. The template file load (include_once) a class file which then fetches all data from database and sends back to template file.

Is there any better way to do this?

Thanks

This sounds fine. Unless you are storing images inside the database or that sort of thing, it should be alright.

You can optimize your queries one by one, but generally the approach you mentioned sounds alright.

...but the problem is, in my script there are too many "include_once".

How many is "too many"?
