Note Submitter: A dot Lepe dev+php at alepe dot com ---- Sorry, my previous comment is mistaken. It should be: You can NOT perform if/elseif/else in one line like this: <?php $c = "c"; echo ($c == "a") ? 1 : ($c == "b") ? 2 : ($c == "c") ? 3 : 0; ?> If we set $c = "b" the result will be still 3. Why? After performing several testings, the real logic behind that line would be more similar to this: <?php $c = "b"; $a = ($c == "a") ? 1 : ($c == "b"); //which in our case will be "true" (as it falls in the false statement). $b = ($a) ? 2 : ($c == "c"); //which will be "2" as $a == true $c = $b ? 3 : 0; //as $b > 0 turns the evaluation "true" and thus the answer is 3. ?> So in order to be able to use if/elseif/else in one line, grouping is required (as it is expected): <?php $c = "b"; echo ($c == "a") ? 1 : (($c == "b") ? 2 : (($c == "c") ? 3 : 0)); //result: 2 ?>
