What PHP framework do you use?

We have built our own tailored MVC framework (pH7Framework) specifically for the needs of pH7CMS.
The framework has 52 main packages containing several different sub-packages.

Finally, pH7CMS uses a homemade template engine (pH7Tpl).The syntax is very similar to Smarty but the library is much lighter is highly optimized (the code is rewrite into optimized PHP code and use static cache as well).
