Hi!

Of course you can. You just missing on what namespace import means in
PHP, it's not like Java (though a bit like Python).

use A is a no-op, just as the warnings tell you. You can just write A\B.
It's only 2 characters more. If your A is longer, then you can alias it
to something shorter.

You could just do
use GlobalNamespace\SubSpace\ThirdSpace as Spc;
$a = new Spc\Class1();
