How can JSON be utilized in PHP to format and return data for jQuery consumption in an AJAX request?

To format and return data for jQuery consumption in an AJAX request, you can use JSON in PHP. JSON is a lightweight data interchange format that is easy to work with in both PHP and JavaScript. You can encode your data in PHP as JSON using the `json_encode()` function and then return it to your jQuery AJAX request. This allows you to easily pass complex data structures between your PHP backend and your JavaScript frontend. 

// Sample PHP code to format and return data as JSON for jQuery AJAX consumption

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

// Encode the data as JSON
$jsonData = json_encode($data);

// Set the content type header to application/json
header('Content-Type: application/json');

// Return the JSON data
echo $jsonData;
