hi Chris, i change the script to: <?php error_reporting(E_ALL); ini_set('display_errors', true); $output = array(); exec('ipkg-cl --version', $output); print_r($output); ?> the output from browser: array() other stuff remain the same. can i conclude php program is not a problem here? i will try to use other server to see if it is server inheritance. and will try to increase errorlog level to see what is the problem. regards,-keo On Mon, Nov 3, 2008 at 1:03 PM, Chris <dmagick@xxxxxxxxx> wrote: > cheesiong wrote: > >> hi Chris, >> thank you. >> it is not working as well. >> i copy the ipkg-cl into /usr/bin >> > > add > > error_reporting(E_ALL); > > and > > ini_set('display_errors', true); > > to the top of your script. > > any errors/warnings/whatever show up? > > > -- > Postgresql & php tutorials > http://www.designmagick.com/ > >
