In the context of PHP usage for interactive applications, what are the benefits of returning JSON objects or arrays instead of simple strings?

When building interactive applications in PHP, returning JSON objects or arrays instead of simple strings allows for more structured and versatile data handling. JSON is a lightweight data interchange format that is easy to parse and manipulate, making it ideal for transmitting complex data structures between the client and server. By returning JSON, you can easily encode and decode data in a standardized format, making it easier to work with in JavaScript or other programming languages. 

// Sample PHP code snippet demonstrating how to return JSON instead of simple strings

$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
);

header('Content-Type: application/json');
echo json_encode($data);
