PHP Switch

This lesson is part of PHP · All levels

Summary

The switch structure is used to select one of many options based on the same value, making it more concise than many if-elseifs. Each option is written with a case, and a break is used so that the execution does not fall on the next case. There are also default blocks that run when there's no matching case.

Key points

Switch compares one variable with many case values
Break stops execution after a case is completed
Default executed if no case matches
Without a break, the execution will fall through to the next case.
