Create PHP Cron Job for Opencart Admin function

Hello, have my own import module for opencart. It imports and updates all products from XML feed of my supplier. Currently I'm using HTTP cron (see attachment). I create copy of admin/[login to view URL] to [login to view URL] and in this file I comment: // Login // $controller->addPreAction(new Action('common/home/login')); // Permission // $controller->addPreAction(new Action('common/home/permission')); It works perfect, CRON job works fine without authentication but I need PHP cron. So what I want from you? Fully functional PHP cron for my import script. Opencart 1.5.6.4.
