PHP Switch Statement

The Switch statement in PHP is used to perform different actions based on a number of different conditions.

You can avoid lengthy if by using the Switch statement frequently. ElseIf. else code block.

Instance

Working principle:

1. Perform a single calculation on an expression (usually a variable)
2. Compare the value of an expression with the value of a case in the structure
3. If there is a match, the code associated with the case is executed
4. After the code executes, the break statement prevents the code from jumping into the next case to continue execution
5. If no case is true, use the default statement
