Example:

$bucket = $storage->bucket('my-bucket');
Parameters
Name Description

The name of the bucket to request.

userProject string|bool

If true, the current Project ID will be used. If a string, that string will be used as the userProject argument, and that project will be billed for the request. Defaults to false.
