How can JSON or XML be used to effectively transfer data between PHP and JavaScript in an Ajax call?

To effectively transfer data between PHP and JavaScript in an Ajax call, JSON or XML can be used as the data format. JSON is commonly preferred due to its simplicity and readability. In PHP, you can encode data into JSON using the json_encode() function, and in JavaScript, you can parse JSON using the JSON.parse() function. This allows for seamless data transfer between the two languages. 

<?php
$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
);

echo json_encode($data);
?>
