What are some potential pitfalls of using multiple nested if statements in PHP code?

Using multiple nested if statements can lead to code that is difficult to read, maintain, and debug. It can also make the code more prone to logical errors and can result in poor performance. To solve this issue, consider using switch statements or refactoring the code to use a different approach, such as polymorphism or a design pattern like the Strategy pattern. 

// Example of refactoring nested if statements using switch statements

$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 "Today is not Monday, Tuesday, or Wednesday";
}
