There is actually a very cool way you can use a switch in PHP to do what
you want:
switch(true)
{
case ($intval >= 2 && $intval <= 11):
{
// stuff here for cases 2-11 inclusive
break;
}
}
Although I think in your case a series of if/else if statements would
work, and might possibly be more readable in your code.
