What are common pitfalls when using if-elseif-else statements in PHP code?

One common pitfall when using if-elseif-else statements in PHP code is not properly structuring the conditions, leading to unexpected behavior or errors. To avoid this, make sure to carefully evaluate the conditions and their order to ensure that they are mutually exclusive. Additionally, using a switch statement can sometimes provide a cleaner and more efficient alternative to if-elseif-else chains. 

// Example of using a switch statement instead of if-elseif-else
$day = "Monday";

switch ($day) {
    case "Monday":
        echo "Today is Monday";
        break;
    case "Tuesday":
        echo "Today is Tuesday";
        break;
    default:
        echo "It's not Monday or Tuesday";
}
