A few days ago Kevin Schroeder showed how to connect the Zend cloud services with the Zend Studio IDE. In this new post he shows how to connect another popular IDE - PHPStorm.
Just because you want to use the Zend Developer Cloud at phpcloud.com doesn't mean that you necessarily use Zend Studio. While I may wonder why you don't use Zend Studio ( :-) ) I know there are a lot of other good IDE's on the market and an IDE like PHPStorm might suit how you do your development.
He walks you through the whole process, complete with screenshots - creating the project on phpcloud, cloning your git repo there, configure PHPStorm for deployment (via SFTP) and set up a little path mapping.
