PHP Switch Statement

Php Switch statement is very useful, it works like if/else statement & reduce the complication of numerous conditions in the script.

Syntax :

switch (expression)
{
case 1
code .. //execute code if expression = 1
break;
case 2
code ... //execute code if expression = 2
break;
default:
code...//execute code if expression not matched
}

Example :

<?php

$value = 6;

switch ($value)

{

case 1:

echo "Value 1";

break;

case 2:

echo "Value 2";

break;

case 3:

echo "Value 3";

break;

default:

echo "Value is " . $value . " not matched!";

}

?>
