The Switch Statement

Use this if you have many codes to be executed and you want to execute only one.

Switch statement takes a single variable as input and then checks it against all different cases you set up for the switch statement then if a match was found then it executes the code otherwise if no match was found then the default case will be executed. Break is also important so that when a match is found, the statement will end right away and will not execute the remaining part of the statement.

Here is the syntax:

switch (variable)
{
case label1:
code to be executed if variable is equals to label1;
break;
case label2:
code to be executed if variable is equals to label2;
break;
default:
code to be executed if variable is not equals to label1 and label2;
}

Here is an example:

<html>
<body>
<?php
switch ($y)
{
case 1:
echo “y equals to 1″;
break;
case 2:
echo “y equals to 2″;
break;
case 3:
echo “y equals to 3″;
break;
default:
echo “y is not equals to 1, 2 or 3″;
}
?>
</body>
</html>
