The San Francisco Symfony Meetup is a forum for open discussion, networking and learning about the best PHP framework out there. The people there generally have an above-average grasp of Symfony so it's a great place to get your questions answered.
"Symfony is a full-stack framework, a library of cohesive classes written in PHP.
It provides an architecture, components, and tools for developers to build complex web applications faster. Choosing Symfony allows you to release your applications earlier, host and scale them without problems, and maintain them over time with no surprise.
Symfony is based on experience. It does not reinvent the wheel: it uses most of the best practices of web development and integrates some great third-party libraries.
Thousands of developers already trust Symfony for their applications!
New users join the community every day, and that makes of Symfony the most popular PHP framework around. A large community means easy-to-find support, user-contributed documentation, plugins, and free applications."
