fatal error: cannot instantiate interface symfony\component\form\formrendererinterface in /var/www/new/test.php on line 193
you're trying instantiate interface:
$form_helper = new formhelper(new formrendererinterface()); interfaces not classes , cannot instantiate them (see http://php.net/interface , read on oop).
check out example of using form component standalone: https://github.com/bschussek/standalone-forms
