How can PHP scripts be adjusted to work with 'register globals = off' setting?

When the 'register_globals' setting is turned off in PHP, it means that variables cannot be automatically registered from the request data (such as form submissions or query parameters). To adjust PHP scripts to work with 'register_globals = off', you need to use superglobal arrays like $_GET, $_POST, or $_REQUEST to access the request data instead of relying on global variables. 

// Instead of using global variables directly, use superglobal arrays
$var = $_POST['variable_name']; // for POST data
$var = $_GET['variable_name']; // for GET data
$var = $_REQUEST['variable_name']; // for both POST and GET data
