In what ways can PHP scripts be optimized to maintain compatibility with future PHP versions and avoid deprecated features like register_globals?

To maintain compatibility with future PHP versions and avoid deprecated features like register_globals, PHP scripts can be optimized by updating code to use superglobal arrays ($_GET, $_POST, $_SESSION, etc.) instead of relying on register_globals. Additionally, it is important to regularly update PHP versions to ensure compatibility with the latest features and security patches. 

// Before optimization
$myVar = $_REQUEST['myVar'];

// After optimization
$myVar = $_GET['myVar'];
