PHP Template Engines?

kubed asks: "I've recently learned how to use PHP template engines to separate business logic from presentation. Some argue that template engines make applications easier to maintain and make for cleaner code. Others argue that template engines introduce unnecessary overhead and require too much additional processing power. Do the readers of Slashdot think that it is important to use templates or are they just an extra unnecessary layer? There are dozens of PHP template engines to choose from including Smarty, phplib, and bTemplate. Which template engines do you have experience with and which ones have the best performance?"

I am currently just two weeks away from going live with a large web application written in PHP using Smarty. I can't speak to performance, as it is a complex application with a low number of clients, but for my needs it has been very acceptable. As far as the interface and syntax, I am in love with Smarty. I had become disenchanted with PHP due to the spaghetti code when you don't use such an engine. Smarty .. mmm, it has brought me back. In fact, I'm writing a templating engine for Ruby based on the Smarty syntax.

Smarty -- highly recommended!

I like template engines

I have a template engine based on standards. It's called XSLT, and it's built into the most recent PHP versions. Especially nice is the 5.x branch, since it has been completely rebuilt for speed and compatibility to libxml2. I have a site full of XML, and I transform it with a central XSL template file into the displayed content. It's a shallow learning curve, and I can change the entire site's layout by a few XSL tweaks. For me, it is the perfect solution.
