What best practices should be followed when developing a PHP CMS system to ensure compatibility with JavaScript components?

When developing a PHP CMS system, it is important to ensure compatibility with JavaScript components by using proper data formats and communication methods. One best practice is to use JSON (JavaScript Object Notation) for data exchange between PHP and JavaScript, as it is a lightweight and widely supported format. Additionally, implementing AJAX (Asynchronous JavaScript and XML) for asynchronous communication between the PHP backend and JavaScript frontend can help improve the user experience and overall performance of the CMS system.

// PHP code snippet to encode data in JSON format
$data = array('key1' => 'value1', 'key2' => 'value2');
$json_data = json_encode($data);
echo $json_data;
