PHP - Switch...case
Introduction
switch...case structure evaluates only one expression, and executes the block depending on its value.
Demo
<?php
$title = "Java";
switch ($title) {
case 'Java':
echo "Nice story.";
break;
case 'Lord of the Rings':
echo "A classic!";
break;
default:
echo "else.";
break;
} //from ww w. j ava 2 s. co m
?>
Result
The switch clause takes an expression, in this case a variable, and then defines a series of cases.
When the case matches the current value of the expression, PHP executes the code inside it.
As soon as PHP finds a break statement, it exits the switch...case.
In case none of the cases are suitable for the expression, PHP executes the default, if there is one, but that is optional.
