How can PHP be used to handle JSON data sent from a cloud service to a server?

To handle JSON data sent from a cloud service to a server using PHP, you can use the `file_get_contents()` function to retrieve the JSON data from the request, and then use `json_decode()` function to parse the JSON string into a PHP array or object for further processing.

// Retrieve JSON data from the request
$json_data = file_get_contents('php://input');

// Parse JSON data into PHP array
$data = json_decode($json_data, true);

// Access and process the JSON data as needed
if ($data) {
    // Handle the JSON data
    // Example: echo the JSON data
    echo json_encode($data);
} else {
    // Handle error in JSON data
    echo 'Error parsing JSON data';
}
