public StreamWrapperInterface::realpath() Returns canonical, absolute path of the resource. Implementation placeholder. PHP's realpath() does not support stream wrappers. We provide this as a default so that individual wrappers may implement their own solutions. Return value string Returns a string with absolute pathname on success (implemented by core wrappers), or FALSE on failure or if the registered wrapper does not provide an implementation.

This is the default 'type' falg. This does not include StreamWrapperInterface::LOCAL, because PHP grants a greater trust level to local files (for example, they can be used in an "include" statement, regardless of the "allow_url_include" setting), so stream wrappers need to explicitly opt-in to this.
