Are there best practices for using switch case statements in PHP for code optimization?

When using switch case statements in PHP, it is important to optimize the code for better performance. One way to do this is by ordering the switch cases based on their likelihood of being executed, with the most common cases at the top. Additionally, using a default case can help handle unexpected input efficiently. Lastly, consider using a switch case statement only when necessary, as sometimes an if-else statement may be more suitable for the task. 

// Example of optimized switch case statement
$day = "Monday";

switch ($day) {
    case "Monday":
        echo "Today is Monday";
        break;
    case "Tuesday":
        echo "Today is Tuesday";
        break;
    // Add more cases in the order of likelihood
    default:
        echo "Invalid day";
}
