Stores and loads PHP code.

Each interface function takes $name as a parameter. This is a virtual file name: for example, 'foo.php' or 'some/relative/path/to/foo.php'. The storage implementation may store these as files within the local file system, use a remote stream, combine multiple virtual files into an archive, store them in database records, or use some other storage technique.
