Nowhere in the documentation does it specify switch should be used in the
context you are attempting.
The docs show a single variable and checking the case of that variable.
I'm not going to berate you on syntax. If you can get it working like that
then good for you. However, I would strongly advise you to use the
if/elseif/else statements instead.
an example of switch
$action = $_POST['action']
switch ($action)
{
case 'help': showHelp(); break;
default : showDefault();
}
not
$action = $_POST['action']
switch (true)
{
case ($action == 'help'): showHelp(); break;
default : showDefault();
}
