How can PHP developers handle the issue of register_globals being set to On by default on hosting servers like 1&1?

The issue of register_globals being set to On by default on hosting servers like 1&1 can be solved by disabling it in the PHP configuration or using alternative methods to access form data. One way to handle this is by using the $_POST or $_GET superglobals to retrieve form data instead of relying on register_globals. 

// Disable register_globals
if (ini_get('register_globals')) {
    $superglobals = array($_REQUEST, $_SERVER, $_FILES, $_ENV, $_COOKIE, $_POST, $_GET);
    foreach ($superglobals as $superglobal) {
        foreach ($superglobal as $key => $value) {
            unset($GLOBALS[$key]);
        }
    }
}
