Need a quick way to parse the name of a class when it's namespaced? Try this:

<?php
namespace Engine;
function parse_classname ($name)
{
  return array(
    'namespace' => array_slice(explode('\\', $name), 0, -1),
    'classname' => join('', array_slice(explode('\\', $name), -1)),
  );
}
final class Kernel
{
  final public function __construct ()
  {
    echo '<pre>', print_r(parse_classname(__CLASS__),1), '</pre>';
    // Or this for a one-line method to get just the classname:
    // echo join('', array_slice(explode('\\', __CLASS__), -1));
  }
}
new Kernel();
?>

Outputs:
Array
(
    [namespace] => Array
        (
            [0] => Engine
        )

    [classname] => Kernel
)
