Are there standardized formats for data exchange in online shop carts that PHP developers should be aware of?

When working with online shop carts, PHP developers should be aware of standardized formats for data exchange such as JSON or XML. These formats allow for seamless communication between the online shop cart and other systems, ensuring compatibility and ease of integration. 

// Example of converting data to JSON format
$data = array(
    'product_id' => 123,
    'quantity' => 2,
    'price' => 19.99
);

$json_data = json_encode($data);

// Example of converting data to XML format
$xml_data = new SimpleXMLElement('<data></data>');
array_walk_recursive($data, array ($xml_data, 'addChild'));
$xml_output = $xml_data->asXML();
