What are some best practices for handling data exchange between PHP and online shop systems to avoid compatibility issues?

When exchanging data between PHP and online shop systems, it is essential to ensure compatibility to avoid issues. One best practice is to use standardized data formats like JSON or XML for data exchange. Additionally, validate input data to prevent errors and sanitize output data to avoid security vulnerabilities. 

// Example of sending data to an online shop system using JSON format
$data = array('product_id' => 123, 'quantity' => 2);
$json_data = json_encode($data);

// Send data to online shop system
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/api');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);
