Namespaced Name

A namespaced name is a name that includes a \ character.

A namespaced name may be relative or absolute.

Namespaced names are sometimes reported in errors.

<?php

namespace B\A {
    class C {}
}

namespace B {
    use A\B as C;
    //import
    new C();

    // relative name
    new A\C(); // actually calls B \ A\C
}

?>
