Global namespace?

php.internals

Assume for some reason you have an entity in a namespace which has the same name as something in the global namespace. Within the namespace, you wouldn't need to use the namespace prefix (maybe it has been aliased, subclassed or some other reference). How would you access the global namespaced entity? For variables, object instances, references, etc., you can use $GLOBALS[], but if the namespace is going to look like ... namespace_a::class_b->method_c(); Should there be an alias for global? global::class_b->method_c(); Or have I missed something?

I believe I read somewhere that it will look like this: ::class_b->method_c(); for accessing global scope. Regards, Emil Ivanov Richard Quadling wrote:

This is the preferred way as it doesn't introduce a new keyword. Also this is inline with other languages.
