Is there any way how to avoid to using so often backslash ?

Now if i\'m using namespace and calling something global inside it i have to use backslash:

Answer 1

constants and functions from the global namespace do not have to be prepended with a backslash. PHP will fallback to the global namespace for those on it's own. There is a whole chapter in the PHP manual explaining this:

• Using namespaces: fallback to global function/constant

Inside a namespace, when PHP encounters a unqualified Name in a class name, function or constant context, it resolves these with different priorities. Class names always resolve to the current namespace name. […] For functions and constants, PHP will fall back to global functions or constants if a namespaced function or constant does not exist.
