What template engine to use?

Question

Drupal

It is necessary to receive value for some expression set by the text.
The text contains variables.
Is there any template engine or built-in functionality in Drupal7 that will allow you to call a function with parameters (template, list of variables) and get a response?
Usage example as I see it:
$tempale = "a+b . ' ' . c";
$res = $templater->render($template, ['a' => 1, 'b' => 7, 'c' => 19]);
As a result of $res = "8 19
" worked out the mathematical function and concatenation.

Answer 1

Drupal doesn't have that.
