How can using associative arrays or references as function arguments improve code readability and maintainability in PHP?

Using associative arrays or references as function arguments can improve code readability and maintainability in PHP by allowing the function to accept a flexible number of parameters without changing its signature. This makes it easier to understand what data is being passed to the function and allows for more straightforward modifications in the future without affecting other parts of the code. 

// Using associative arrays as function arguments
function processUserData(array $userData) {
    $username = $userData['username'];
    $email = $userData['email'];
    
    // Process user data
}

$userData = [
    'username' => 'john_doe',
    'email' => 'john.doe@example.com'
];

processUserData($userData);
