How can JSON encoding be used to improve data exchange between PHP and JavaScript in web applications?

JSON encoding can be used to improve data exchange between PHP and JavaScript in web applications by converting PHP data structures into a format that is easily readable by JavaScript. This allows for seamless communication between the two languages, making it simpler to pass data back and forth. By encoding PHP data into JSON format, you can ensure that the data is properly formatted and can be easily parsed by JavaScript on the client side. 

// Sample PHP code snippet demonstrating JSON encoding for data exchange
$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
);

// Encode PHP data into JSON format
$json_data = json_encode($data);

// Pass the JSON data to JavaScript
echo "<script> var jsonData = $json_data; </script>";
