What are the potential pitfalls of using nested if-else constructs in PHP code?

Using nested if-else constructs can lead to code that is difficult to read, maintain, and debug. It can also result in code that is less efficient and harder to extend in the future. To solve this issue, consider using switch statements or refactoring the code into separate functions to improve readability and maintainability. 

// Example of refactoring nested if-else constructs into separate functions

function processInput($input) {
    if ($input === 'A') {
        handleCaseA();
    } elseif ($input === 'B') {
        handleCaseB();
    } else {
        handleDefaultCase();
    }
}

function handleCaseA() {
    // Code to handle case A
}

function handleCaseB() {
    // Code to handle case B
}

function handleDefaultCase() {
    // Code to handle default case
}

// Call the function with the input
$input = 'A';
processInput($input);
