Declaring sub-namespaces
(PHP 5 >= 5.3.0, PHP 7)
Much like directories and files, PHP namespaces also contain the ability to specify a hierarchy of namespace names. Thus, a namespace name can be defined with sub-levels:
Example #1 Declaring a single namespace with hierarchy
<?php
namespace?MyProject\Sub\Level;
const?CONNECT_OK?=?1;
class?Connection?{?/*?...?*/?}
function?connect()?{?/*?...?*/??}
?>
The above example creates constant MyProject\Sub\Level\CONNECT_OK, class MyProject\Sub\Level\Connection and function MyProject\Sub\Level\connect.
