What are the disadvantages of using complex and difficult-to-read code structures, such as the one shared in the forum thread?

Using complex and difficult-to-read code structures can lead to several disadvantages, such as decreased code maintainability, increased likelihood of bugs and errors, difficulty in understanding and debugging the code, and reduced efficiency in development and collaboration. To solve this issue, it is important to refactor the code to make it more readable, modular, and easier to understand for yourself and other developers.

// Original complex and difficult-to-read code structure
function complexFunction($param1, $param2) {
    // Complex logic here
    if ($param1 > $param2) {
        // More complex logic
        return $param1 * $param2;
    } else {
        // Even more complex logic
        return $param1 + $param2;
    }
}

// Refactored code for improved readability
function simplifiedFunction($param1, $param2) {
    $result = $param1 + $param2;
    
    if ($param1 > $param2) {
        $result = $param1 * $param2;
    }
    
    return $result;
}
