I have recently been learning regular expressions, and thought I was "fresh" enough to fix this with new eyes. However, I've been running into all kinds of trouble, and I now impatiently anticipate an expert's answer, much the same as you. :) It's interesting to me that `$st = preg_replace("(SUN)", "FRIKI", $st); replaces the word "SUN" with the word "FRIKI", but $st = preg_replace("(^SUN)", "FRIKI", $st);` does the same thing (when it should be replacing everything BUT the word "SUN"). Annoying behavior. Is this particular to PHP's regular expression engine? I should try this in VB.NET and see what the results are, as that's what I'm used to playing with (for the time being).
