That's not all, though - ZPT also comes with a couple of low-key loop constructs that allow you to iterate over sequences of both variables and objects. This ability to create loops is not unique to ZPT - almost every programming language on the planet allows you to do this - but as with DTML, ZPT includes some fairly interesting twists to the traditional approach. Let's take a look.

How to do Everything with PHP & MySQL
