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

Using nested if statements can lead to code that is difficult to read and maintain, as it can quickly become complex and hard to follow. To avoid this, consider using alternative control structures like switch statements or ternary operators. Additionally, breaking down complex conditions into separate functions or using early returns can help improve the readability of your code. 

// Example of refactoring nested if statements using switch statement

$grade = 'B';

switch ($grade) {
    case 'A':
        echo 'Excellent';
        break;
    case 'B':
        echo 'Good';
        break;
    case 'C':
        echo 'Average';
        break;
    default:
        echo 'Fail';
}
