I always wondered how good it would be to have a Cloud IDE where i could host all my PHP files, test it, share it etc. basically it should be able to do everything which i do in my Computer. and until recently i stumbled upon a very nice Cloud IDE called Kodingen. it is such a useful Cloud Application and so handy at times. however below is the list of some of the services which offers you to run PHP code.
