Hello Weiting,

Looking at the error message:

RuntimeError: Unknown runtime 'php'; supported runtimes are 'custom', 'go', 'java', 'java7', 'php55', 'python', 'python-compat', 'python27'.

It seems your app.yaml file isn't setup correctly. As Google App Engine currently only supports PHP 5.5, please make sure the runtime is listed inside app.yaml as

runtime: php55

I hope it helps. Cheers!
