At this year's ZendCon conference a new technology was introduced (well, and upgrade to an existing product) that allows PHP developers to create Android applications from Zend Studio 10.

ZendCon, the annual trade show for Zend, the PHP company, announced that Zend Studio 10 (Zend's IDE) will include functionalities that will let PHP developers prototype and build native mobile apps using PHP. The new capability includes a drag-and-drop mobile interface builder, integration with the Apache project's Cordova to access native mobile APIs such as those for cameras and accelerometers, and built-in PhoneGap integration for developers to publish native app packages to the various app stores.
