Is there a way to make this syntax:

$checking_answer = $answer_reference_2;

Equal to:

$checking_answer = $answer_reference_ . ($i + 1);

(where $i = 1)

making $checking_answer take on the value of $answer_reference_2 ?

I am trying to develop a web app quiz and I need to test the users answers.
