Eclipse: Automatically add "use namespace"

Question

I am refactoring a big PHP project (more than 500 PHP files) into namespace tree structure.

Is there a way to get Eclipse PDT automatically add use ... at the top of the file when an undefined class is encountered?

Otherwise: is there a way to get Eclipse PDT highlight undefined classes, so that i can do sort of right click -> add namespace, like in Microsoft Visual Studio?

Thank you

Eclipse will not add use statement on save, only while ctrl+space.

You can install Pex-Core plugin. It have class usage validator and quick assist (ctrl + 1) "inject use statement". Available at http://p2.pdt-extensions.org
