What are some potential pitfalls of using indirection in PHP?

Using indirection in PHP can lead to decreased code readability and maintainability, as it can make it more difficult to follow the flow of the program. Additionally, it can introduce unnecessary complexity and potentially create security vulnerabilities if not implemented carefully. To mitigate these pitfalls, it's important to use indirection sparingly and only when necessary, ensuring that it adds value to the codebase without sacrificing clarity or security. 

// Avoid excessive use of indirection
function processUserData($data) {
    // Directly access the data properties
    $name = $data['name'];
    $email = $data['email'];
    
    // Process the data
    // ...
}
