I think every question should have an answer, so I'm posting here as well. Feel free to accept the answer someone else posted there just now.

htmlentities($str, ENT_QUOTES); or htmlspecialchars($str, ENT_QUOTES); should do the trick where $str should be replaced by the variable or string you want to escape (e.g., $row[0]). If you just want to add it, all you need to do is add it: print "Here's an apostrophe '";
