Ok, sorry. I misread your report a bit ;)
So this applies only to RISC OS ? Can't reproduce this under linux.

Jesus man.
case statements not followed by a break; statement fall through.
Your code should read:
<? $k = "+";
switch($k) {
case "-": print "Oh no!"; break;
case "+": print "Correct!"; break;
}
?>

<? $k = "+";
switch($k) {
case "-": print "Oh no!";
case "+": print "Correct!";
}
?>
outputs "Oh no!". I guess this is because as switch uses
==, + and - are both being automatically converted to the
number 0 which then matches? Could switch() perhaps use
=== instead of == in its comparison?
