KnpUniversity (now known as SymfonyCasts) is a US-based PHP / Symfony training platform run by Ryan Weaver, a Symfony core team member. The platform is the closest thing to an official video-tutorial source for the Symfony framework — Ryan's tutorials are the path most working Symfony developers learned the framework through.
The CourseFlix listing carries two KnpUniversity courses: Learn Symfony 3 and PHPUnit — Testing with a Bite. Material is paid and aimed at PHP developers picking up Symfony or PHPUnit testing.
