Why getting Parse error: syntax error, unexpected T_OBJECT_OPERATOR?

[ghurty]

Why would I be getting a

Parse error: syntax error, unexpected T_OBJECT_OPERATOR

 

 

on the first line of this code?

if(!empty($_GET['designModeToken']) && getClass('ISC_ADMIN_AUTH')->isDesignModeAuthenticated($_GET['designModeToken'])) {
isc_setCookie('designModeToken', $_GET['designModeToken'], 0, true);
ob_end_clean();
header('Location: '.getConfig('ShopPathNormal'));
exit;
}

Because the getClass function doesn't return an object.

What version of PHP are you running? That syntax isn't valid below PHP 5.
