• The expression is evaluated once

• The value of the expression is compared with the values of each case

• If there is a match, the associated block of code is executed
• The break keyword breaks out of the switch block
• The default code block is executed if there is no match
Example
The break Keyword
When PHP reaches a break keyword, it breaks out of the switch block.
This will stop the execution of more code, and no more cases are tested.

The last block does not need a break, the block breaks (ends) there anyway.
