On the Symfony blog they have a new post announcing the upcoming SymfonyLive Paris event and that there are still Early Bird tickets available. As the event is in Paris the post is in French (but Google Translate easily fixes that).
The SymfonyTour 2018 makes another stop in the city of light with the SymfonyLive Paris 2018 conference ! The key event of the French-speaking community Symfony will celebrate its 10th edition on March 29 and 30, 2018 at the Cité Internationale Universitaire in Paris.Come share and interact with other members of the community and attend talks to let you discover the latest developments in the framework and improve the development of your web projects!
There will be two days of pre-conference training available (the 27th and 28th) at the SensioLabs offices. You can purchase tickets either for the Training+Conference or just for the Conference. The Early Bird rate will only last until January 14th and if you're interested in presenting the Call for Papers is open until January 21st.
