Symfony Undefined namespace

Question

I am seeing namespace errors all over the place and I am not sure why.

For exampe I have: use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; and Configuration is in red and the error reads:

Undefined namespace Configuration less... (Ctrl+F1) 
Referenced namespace is not found.

How do I fix this?

Answer 1

Since you say "Configuration is in red" I assume the problem you are experiencing is related to the IDE

If you are using PHPStorm there's a specific Symfony plugin that handle all the namespacing pretty much automatically, as long as your setup is standard. By standard I mean a project dir containing the app/ src/ web/ ... dirs (if you're using the 2.x Symfony dir layout)
