How can PHP be used to create a system that retrieves and processes data from external sources like a library's user system?

To create a system that retrieves and processes data from an external source like a library's user system, you can use PHP to make API requests to the external source, retrieve the data, and then process it accordingly within your system. 

<?php
// Make a request to the external source's API
$data = file_get_contents('http://external-source.com/api/users');

// Decode the JSON response
$users = json_decode($data, true);

// Process the retrieved user data
foreach ($users as $user) {
    echo 'User ID: ' . $user['id'] . '<br>';
    echo 'Name: ' . $user['name'] . '<br>';
    echo 'Email: ' . $user['email'] . '<br>';
    // Additional processing logic here
}
?>
