The Switch Statement

If you want to select one of many blocks
of code to be executed, use the Switch statement.

The switch statement is used to avoid long blocks of if..elseif..else code.

Syntax

switch (expression)
{
case label1:
  code to be executed if expression = label1;

  break;  
case label2:
  code to be executed if expression = label2;
  break;
default:
  code to be executed
  if expression is different 
  from both label1 and label2;
}

Example

This is how it works:

A single expression (most often a
variable) is evaluated once

The value of the expression is compared with the values for each case in
the structure

If there is a match, the code associated with that case is executed

After a code is executed, break is used to stop the code from
running into the next case

The default statement is used if none of the cases are true

<html>
<body>

<?php
switch ($x)
{
case 1:
  echo "Number 1";
  break;
case 2:
  echo "Number 2";
  break;
case 3:
  echo "Number 3";
  break;
default:
  echo "No number between 1 and 3";
}
?>

</body>
</html>
