我可以使用适用于PHP SDK的Google应用程序引擎调用“ mkdir”功能吗？

Question

Could I call "mkdir" function with Google app engine for PHP SDK?

I have tried with the living GAE for PHP, seems failed to create the directory.

Answer 1

You can't create directory during runtime on GAE.

Take a look at the GAE's introduction . In the The Sandbox paragraph, it says:

Applications cannot write to the file system in any of the runtime environments. An application can read files, but only files uploaded with the application code. The app must use the App Engine datastore, memcache or other services for all data that persists between requests.

I think that's why you failed to create the directory.
