What best practices should be followed when using switch statements in PHP?

When using switch statements in PHP, it is important to follow best practices to ensure clean and readable code. One key practice is to always include a default case to handle unexpected values. Additionally, it is recommended to use break statements at the end of each case to prevent fall-through behavior. Lastly, consider using switch statements for situations where there are multiple conditions to check against a single variable. 

// Example of using switch statement with best practices
$day = "Monday";

switch ($day) {
    case "Monday":
        echo "Today is Monday";
        break;
    case "Tuesday":
        echo "Today is Tuesday";
        break;
    case "Wednesday":
        echo "Today is Wednesday";
        break;
    default:
        echo "Invalid day";
}
