194.***.***.***PHP Switch Statement
The Switch StatementIf 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
Code:
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
Code:
<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>
