What are the differences between JSON and JSONP in PHP, and how should they be handled differently?

JSON is a data format commonly used for exchanging data between a server and a web application. JSONP, on the other hand, is a technique used to overcome the cross-origin restrictions when making AJAX requests. In PHP, JSON data can be easily encoded and decoded using the json_encode() and json_decode() functions, while JSONP requires wrapping the JSON data in a callback function to allow for cross-origin requests. 

// JSON example
$data = array("name" => "John", "age" => 30);
$json_data = json_encode($data);

// JSONP example
$data = array("name" => "John", "age" => 30);
$json_data = json_encode($data);
$callback = $_GET['callback']; // get the callback function from the request
echo $callback . '(' . $json_data . ')';
