SIMPLE Perl Regex

Sorry for the noob question, but I am new to Perl and cannot seem to wrap my head around my regex's evaluating to the opposite of what they seemingly should. I am trying to do a simple verification that user input is either a 0 or a 1.

Why is this evaluating to 'it matches'?
if('asdf' == /^[01]$/){
            $temp = 'it matches';
      } else {
            $temp = 'it doesnt match';

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

change ==
to: =~

== is the numerical equality test operator
=~ is the binding operator needed to bind the regex to the string for matching
