“Symfony2 vs Yii2 framework— which one is better?” is a question with no answer. But, according to our observations, Yii2 is loved for its simplicity and fast performance, as well as solid MVC architecture. Easy-to-learn API is also often mentioned among its strengths. As for the drawbacks, routing in Yii2 isn’t very powerful. Big amount of widgets can also influence the learning curve.
Advantages of Symfony2 include flexible routing, in-build cache system, as well as Twig usage (but there’s a way
to use Twig template engine in Yii2
). A large number of entities is often considered a drawback of Symfony2. And annotation syntax has its objectors too.
Easy installation, namespaces, good testing capabilities and a number of extensions are peculiar to both frameworks. But in the end the best way to choose between Symfony2 and Yii2 is to install them both, try to write an application and see what will work for you.
