Another option for API class versioning is to set the classname as a variable conditionally.

// Get class name
switch ($api_version) {
  case 'v0':
    // No class namespace
    $class = 'Handler';
    break;
  case 'v1':
    // Namespaced class
    $class = 'API\App\v1\Handler';
    break;
  case 'v2':
    // Namespaced class
    $class = 'API\App\v2\Handler';
   break;
 default:
   throw new Exception('Unknown API version: ' . $api_version);
}
// Get class object
$handler = new $class();
