Question

A switch statement consists of “cases”…

But is there any “else” case for all other cases?

Have never found the answer to this…

ex:

 switch ($var){
   case "x":
       do stuff;
   break;
   case "y":
       do stuff;
   break;
   else: // THIS IS WHAT I WOULD LIKE
       do stuff;
   break;
 }

Answer 1

default:
       do stuff;
break;

Typically the default clause should be at the very end of your other case clauses for general readability.

You may also want to reformat your break statements in your code to look like this:

 switch ($var){
   case "x":  // if $var == "x"
       do stuff;
       break;
   case "y":  // if $var == "y"
       do stuff;
       break;
   default:  // if $var != "x" && != "y"
       do stuff;
       break;
 }
