The instant gratification framework
PiePHP is a rapid development framework for PHP which significantly speeds web application development. It includes a code generator, a database generator, a documentation helper, and a functional testing suite.
Speed
PiePHP has the fastest page rendering time of any major PHP framework.
Persistent page
The PiePHP JavaScript library can AJAXify your links and forms, so the page shell doesn't need to re-render as users browse. That means you can put media players or chat widgets or whatever you want into your page, and they won't need to stop.
Environments
PiePHP supports development, test, staging and production environments to make your development environment flexible and your live site secure.
Auto-refresh
When you save changes in your IDE, your PiePHP development environment can cause your pages to refresh in every browser window. What better way to optimize the change & verify cycle?
Error editing
In a development environment, errors are shown as editable code blocks. So you can fix the error and move on quickly without even leaving the page.
