Good evening, I also need someone to help me with a small PHP code.

Something needs to be implemented on the website. I will provide more details so you can understand. It is related to a PHP Achievement System code. I will also post some pictures for reference. For example, the first picture is from the website, which works perfectly, and I want to add that system from the picture to the application. The application uses the same index.php, HTML, and JavaScript as the website, and I want it to function the same way. The Achievement system from the website should also work in the application. The application already has this system, but it's not connected to the website
