bucket

Lazily instantiates a bucket.

There are no network requests made at this point. To see the operations that can be performed on a bucket please see Google\Cloud\Storage\Bucket.

If $userProject is set to true, the current project ID (used to instantiate the client) will be billed for all requests. If $userProject is a project ID, given as a string, that project will be billed for all requests. This only has an effect when the bucket is not owned by the current or given project ID.

Example:

$bucket = $storage->bucket('my-bucket');

Parameters
Name	Description
`name`	`string` 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`.

Returns
Type	Description
`Google\Cloud\Storage\Bucket`
