Confused about content size / limit

I'm building PHP scripts to return database query content, and am confused about the WAP imposed limit on returned content. As I thought I understood it, a card was limited to 1K of data, but looking at my Apache logs, 2K and 4K chunks of data are being sent back for display.

The problem is that I don't want the phone to crash with a content-too-large message, so I will need to split up the results before they are sent out.

Or, is it that each card is limited to 1K in which case I could create "n" cards and stick 'em all in one deck ? You can see why I'm confused!

Hi I got a similar problem, I'm not that great with programming can someone please tell me how to split a large db to display in multiple pages, anyone have some code to share.
Thanks
