You can only match 1 possible value of the test variable with each case 
statement in php.

You can not match multiple possible values of the test variable in a 
single case statement in php.

If you wish to match multiple values, you can stack case statements.

The case statement comparison is a coercive equality test, ie it will 
coerce both objects being compared so that it can make a meaningful test 
for equality.

Here is an example of multiple tests all executing the same code branch 
in a switch statement:

switch ( $x ) {

	case "fish":
	case "chips":
	case "sausages":
	case "peas":
	case "beans":
	case "burgers":
		echo "food";
		break;

	case "salt":
	case "pepper":
	case "vinegar":
	case "ketchup":
		echo "Condiment";
		break;

	case "water":
	case "beer":
	case "whisky":
	case "vodka":
	case "cola":
	case "milk":
	case "coffee":
		echo "beverage";
		break;

	default:
		echo "Are you sure you want to consume that?";
		break;

}

I eagerly await your next example of how to fuck up a switch statement.
