You have a valid point; Perl is not a silver bullet. Even those of us who believe that Perl is a better language than PHP in every way must reluctantly acknowledge that switching languages is not the solution to every problem. :)

Whether this means someone "should" stick with PHP is more debatable, and depends on their personal learning style. Some people find gradual learning easier than rapid change, and if kitsune's that sort of person then sticking with PHP might be helpful. On the other hand, some people find a clean break helpful; it instantly gets them away from any existing bad habits, and it forces them to learn the new approach properly instead of falling back on their old tried-and-tested approaches when the going gets tough. If kitsune is that sort of person, then switching to Perl now would be best.
