 to have a helper function, say `get_namespace()`, which has the additional=

Hi, Claude,

That's sound great. Something like dirname[1] but with namespaces.

But...in that case, I also add a new function like basename but with namesp=
aces. Example autoload for WordPress :

```
function autoload( $ful_class_name ) {

$class_ path =3D str_replace('\\', '/', get_namespace( $ful_class_name ) );
$class_name =3D strtolower( get_base_namespace( $ful_class_name ) );

  require "{$class_path}/class-{$class_name}.php";

}```
