PHP : Does extending class need another 'use' to call namespace?

php class inheritance namespaces extend

I'm wondering whether in the situation where I'm extending a class that has already 'use' keyword above it to use specific namespace - do I need to add another 'use' above the inheriting class to use the same namespace? Situation like this:

namespace Core;

use System\Plugin;

class Front extends Application { }

and now in the Controller, which is called directly without the namespace (using full path):

use System\Plugin;

class PageController extends Front { }

or would it work without 'use' as well and allow me to use the System\Plugin namespace:

class PageController extends Front { }

?

No, you need the "use" statement in both files. Use is a file-level keyword and isn't affected by inheritance.

See the scoping rules for importing and the little box describing what I said at the bottom of the manual page.
