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.
