You can achieve what you're trying to do already with a combination of
get_class() on a namespaced class and a simple regex (or other method of
processing a string to your liking):
$foo = "My\\Namespace\\Name\\Class";
var_dump(preg_match('/^(.*)\\\([^\\\]*)$/m',$foo,$matches),$matches);
array(3) {
[0] =>
string(23) "My\Namespace\Name\Class"
[1] =>
string(17) "My\Namespace\Name"
[2] =>
string(5) "Class"
}
