PHP Switch Case

The switch statement is used to perform different actions based on different conditions. It is an alternative to multiple if-elseif statements.

Example:

<?php
    $day = "Tuesday";

    switch ($day) {
        case "Monday":
            echo "Start of the week!";
            break;

        case "Tuesday":
            echo "Second day of the week.";
            break;

        case "Wednesday":
            echo "Mid-week day.";
            break;

        case "Thursday":
            echo "Almost weekend!";
            break;

        case "Friday":
            echo "Weekend starts tomorrow!";
            break;

        default:
            echo "Weekend!";
    }
?>

Switch Case Without Break (Fall-Through):

<?php
    $num = 2;

    switch ($num) {
        case 1:
            echo "One";

        case 2:
            echo "Two"; // This will also run because break is missing above
            break;

        case 3:
            echo "Three";
            break;
    }
?>
