he theme engine PHPTemplate has been removed from Drupal. Drupal will continue to support alternative theme engines, but only Twig will be include with core.

Be aware that if you use an alternative theme engine, you will need to provide some means of escaping unsafe output. This is handled in Drupal core by Twig's autoescape.
