How can developers ensure the security and stability of PHP scripts when making adjustments to accommodate different server settings like "register_globals"?

When making adjustments to accommodate different server settings like "register_globals", developers can ensure the security and stability of PHP scripts by updating their code to use superglobal arrays like $_GET, $_POST, and $_SESSION instead of relying on register_globals. This helps prevent security vulnerabilities and ensures compatibility with newer PHP versions. 

// Before adjusting for register_globals
$my_var = $_REQUEST['my_var'];

// After adjusting for register_globals
$my_var = isset($_GET['my_var']) ? $_GET['my_var'] : '';
