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

Using nested if-else statements can lead to code that is difficult to read, maintain, and debug. It can also result in code that is prone to errors and can be inefficient in terms of performance. To avoid these pitfalls, consider using switch statements or refactoring the code to use a more structured approach, such as using functions or classes. 

// Example of refactoring nested if-else statements into a more structured approach

// Original nested if-else statements
if ($condition1) {
    if ($condition2) {
        // Code block
    } else {
        // Code block
    }
} else {
    // Code block
}

// Refactored code using functions
function condition1Function() {
    if ($condition2) {
        // Code block
    } else {
        // Code block
    }
}

if ($condition1) {
    condition1Function();
} else {
    // Code block
}
