As a developer using the NDS Labs platform, I should be able to easily edit, run, and debug PHP code.

Useful features might include:

• Command line applications
• Web-based applications
• Interactive debugging

Although plenty of options exist, Cloud9 seems to be a good jumping-off point.

This ticket can be closed when a suitable PHP development environment has been packaged as an NDS Labs service spec pointing to a tagged Docker image (i.e. not "latest"). Ideally, we can demonstrate using this environment to modify an existing NDSC application such as Hubzero.
