In what situations should parameters in a PHP function be grouped or passed as an array/object instead of individually?

When a PHP function requires a large number of parameters or when the parameters are related and logically grouped, it is more efficient to pass them as an array or object instead of individually. This approach can make the code cleaner, more organized, and easier to maintain. It also allows for easier expansion of the function's capabilities without changing its signature. 

// Example of passing parameters as an array in a PHP function

function processUserData($userData) {
    $name = $userData['name'];
    $age = $userData['age'];
    $email = $userData['email'];

    // Process user data here
}

$userData = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
];

processUserData($userData);
