I changed the composer dependency on Symfony to support 3.0. It looks like your library works out of the house with Symfony 3.0. The unit tests are working and I generated a document to test it.
Furthermore, I made a change to support PHP7. Within PHP7, substr() returns an empty string if the length of the input string equals the start position.
