SCNR
Having several `case CONSTANT:` with the same CONSTANT is ok? :)


<?php
$var = true;

echo "First set: ";
switch ($var) {
default: echo 'No variables in the list are'; break;
case isset($a): echo 'a is'; break;
case isset($b): echo 'b is'; break;
case isset($c): echo 'c is'; break;
case isset($d): echo 'd is'; break;
}
echo " set.\n";

$b = $c = 42;
echo "Second set: ";
switch ($var) {
default: echo 'No variables in the list are'; break;
case isset($a): echo 'a is'; break;
case isset($b): echo 'b is'; break;
case isset($c): echo 'c is'; break;
case isset($d): echo 'd is'; break;
}
echo " set.\n";
?>
