If I understand correctly, all you need to do is add OpenGraph on your PHP/HTML header.

    <meta property="og:title" content="Your desired title" />
    <meta property="og:description" content="Some sentences here" />
    <meta property="og:url" content="https://www.yourdomain.com/filename.php" />
    <meta property="og:site_name" content="rumahweb.com" />
    <meta property="og:image" content="https://www.yourdomain.com/featured-image.png" />

Insert above code (and adjust the value as necessary) inside your HEAD section of your HTML/PHP file.
