I have been wrestling with drupal, css, php, and twig all day today. I don’t consider myself a programmer. Someone else invented these languages.
I'm not familiar with twig, but the others I do not consider to be programming languages. They are more of a markup/formatting protocol. PHP does some processing of data, but it's not a General Purpose programming language.
I've done a lot of COBOL, some C/C++, some python, and a very tiny bit of Perl. I think the key to remember is that once you learn how to program in the abstract, then whatever language you choose is just syntax.
