How can JSON be used to simplify data transfer between PHP and JavaScript?

JSON can be used to simplify data transfer between PHP and JavaScript by encoding PHP data into a JSON format that can be easily parsed by JavaScript. This allows for seamless communication between the two languages without the need for complex data conversion methods. To implement this, PHP can use the json_encode() function to convert PHP arrays or objects into a JSON string, which can then be sent to JavaScript for processing. 

<?php
$data = array("name" => "John", "age" => 30, "city" => "New York");
$json_data = json_encode($data);
echo $json_data;
?>
