The switch-case statement is an alternative to the if-elseif-else statement, which does almost the same thing.

Syntax

switch(n){
    case "person1":
        // Code to be executed if n=person1
        break;
     case "person2":
        // Code to be executed if n=person2
        break;
    ...
    default:
        // Code to be executed if n is different from all 
}

Consider the following case, which displays a different message for each day.

#example.php

<?php
$today = date("D");
switch($today){
    case "Mon":
        echo "Today is Monday. Clean your house.";
        break;
    case "Tue":
        echo "Today is Tuesday. Buy some food.";
        break;
    case "Wed":
        echo "Today is Wednesday. Visit a doctor.";
        break;
    case "Thu":
        echo "Today is Thursday. Repair your car.";
        break;
    case "Fri":
        echo "Today is Friday. Party tonight.";
        break;
    case "Sat":
        echo "Today is Saturday. Its movie time.";
        break;
    case "Sun":
        echo "Today is Sunday. Do some rest.";
        break;
    default:
        echo "No information available for that day.";
        break;
}
?>
