Switch()

[Cod-nes]

I'm having problems with switch(). The script works fine when I only put one value. But when I try to do two values it executes something weird. When the $ns=s2, it executes case "s1" or another case.

$ns=$GET["ns"];switch ($cookie || $ns){case "s1":echo $sr1;break;case "s2":echo "hi";break;case "s3":echo $sr3;break;case "s4":echo $sr4;break;case "s5":echo $sr5;break;case "s6":echo $sr6;break;case "s7":echo $sr7;break;default:echo "hi";}

How does switching for the value ($cookie or $ns) work? This will return true or false, depending on the values, and if true will execute the "s1" case, and if false will use default.I don't understand what you are trying to achieve with the or operator...

|| returns a boolean value. Non-boolean values are cast as boolean and called "truthy" or "falsy." Strings are only falsy when empty.

switch (empty($cookie) ? $ns : $cookie)

This uses a boolean correctly and achieves the result which I consider the most humanly reasonable for the given code. See the ternary operator.
