How can structured output formats like JSON be used to facilitate data transfer between PHP and JavaScript in a webpage?

Structured output formats like JSON can be used to facilitate data transfer between PHP and JavaScript on a webpage by allowing data to be easily serialized and deserialized in a format that both languages can understand. This can be particularly useful when passing complex data structures between the two languages, such as arrays or objects. In PHP, you can use the `json_encode()` function to convert data to JSON format, which can then be accessed in JavaScript using the `JSON.parse()` function. 

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

echo json_encode($data);
?>
