Is there a sandbox or test environment available for PHP developer for Cloud services

I am looking for sandbox or test environment where I can learn:

How to deploy PHP applications on Cloud and learn about the basic of Cloud computing.

Like Paypal has sandbox for developers. Is there any such test environment exists for P开发者_如何学CHP programmers? I would like to know the path I should follow to gain knowledge in cloud readiness based on PHP.

Just to make it clear, I am looking for free service. If free or testing place is not available then very cheaper service is also good to know for developers point of view.

i would suggest trying Amazon Web Services as from some time they offer free usage tier for users http://aws.amazon.com/free/

We offer a free tier. You can have multiple apps and deployments for free within certain limits (max 1 box per hour and the limits of the free add-on options you may choose).

Feel free to try it at http://cloudcontrol.com and if you have any questions I'm around and happy to answer them.
