Is json_encode() the best practice for converting database content to JSON data in PHP for inter-server communication?

To convert database content to JSON data in PHP for inter-server communication, using json_encode() is a common and efficient practice. This function converts a PHP array or object into a JSON string, which can then be easily transmitted between servers or applications. It ensures that the data is properly formatted and structured for easy parsing and handling on the receiving end.

// Assuming $data is an array containing database content
$jsonData = json_encode($data);

// Send the JSON data to another server using cURL or any other method
