Hi all .. its all nice going till i needed to Zip a folder on my server.. all ok .. zippinf well .. extracting well but ... ziped file is taking complete absolute url for the zipped folder. I just need to take zip file=>having my targeted folder..

$this->load->library('zip');
        $this->zip->read_dir($tmpComp.DS);
        $zip_file = $this->zip->get_zip();
