As mentioned in this post to the Symfony blog, they've posted the full schedule for the Symfony Live Paris 2013 event. This year's event includes sessions like:

• The PHP Content Repository PHPCR (David Buchmann)
• Git Flow: an Agile Development Process (Xavier Hausherr)
• Understanding the heart of Component Security (Rouff Joseph)
• How to organize your templates twig? (Gregory Pineau)
• Integrate forms and validation in your PHP applications (Hugo Hamon)

You can still get your tickets for thus year's event too- they're the "last minute" tickets and will cost about 300 Euro, but there's still some left!
