I am not speaking about statements "outside" of a namespace (which is not possible as you mentioned as well). I am speaking about "use declarations" outside of a namespace and with outside I mean actually outside. As you mentioned, when one tries to do the following $a = 1; namespace test; This will fail because $a is outside of a namespace (you will get the error message "Namespace declaration statement has to be the very first statement in the script") Maybe it was not clear enough, so I am going to rewrite my example to be clearer: namespace{ //default namespace $a = 1; } use foo\Bar; namespace test{ new Bar(); } I hope that clears things up.
