PHP Switch

The switch statement is an efficient alternative to multiple if-elseif branches.

Syntax

switch ($day) {
    case "Monday":
        echo "Start of week";
        break;
    case "Friday":
        echo "Weekend near";
        break;
    case "Saturday":
    case "Sunday":
        echo "Weekend!";
        break;
    default:
        echo "Midweek";
}

Key Points

• Use break to prevent fall-through
• default handles unmatched values
• Use match (PHP 8+) for strict comparison with return values
