How can PHP developers ensure their scripts are independent of the register_globals setting?

When the register_globals setting is enabled in PHP, it can lead to security vulnerabilities by allowing external variables to overwrite script variables. To ensure scripts are independent of this setting, developers should use superglobal arrays like $_GET, $_POST, and $_REQUEST to access external variables instead of relying on register_globals. 

// Example of how to ensure scripts are independent of the register_globals setting

// Instead of using $variable directly, use $_POST['variable'] or $_GET['variable']
$variable = isset($_POST['variable']) ? $_POST['variable'] : '';

// Use superglobal arrays to access external variables
