1 file_example.module file_example_stream_wrappers()

Implements hook_stream_wrappers().

hook_stream_wrappers() is Backdrop's way of exposing the class that PHP will use to provide a new stream wrapper class. In this case, we'll expose the 'session' scheme, so a file reference like "session://example/example.txt" is readable and writable as a location in the $_SESSION variable.
