Breaking out

As you can see in Example 15-14, just as with PHP, the break command allows your code to break out of the switch statement once a condition has been satisfied. Remember to include the break unless you want to continue executing the statements under the next case.

Default action

When no condition is satisfied, you can specify a default action for a switch statement using the default keyword. Example 15-15 shows a code snippet that could be inserted into Example 15-14.
