Maguma's products are no longer developed, maintained or supported. Here are some alternatives.

The best professional editor is currently Zend Studio from Zend Technologies. Similar to what Maguma had in mind, the Zend Studio can integrate wit a server side development and deployment platform, the Zend Server.

NuSphere also has a more basic PHP editor called PhpEd. Balanced combination of code editor, debugger, database connectivity client and fast and secure deployment abilities make PhpED a complete solution for most developer needs.

An interesting twist on PHP editors is Delphi for PHP, a integrated, rapid visual development approach and component framework for PHP.
