  hi! im new here. im still starting to explore php codes. and now im doing a program in uploading files.
  

  
  i used to upload an image in the server
  

  
  $uploadfile = "/var/www/images/";
  moveuploadedfile($FILES['filefield']['tmpname'], $uploadfile);
  

  
  then i used
  chmod($uploadfile, 0777);
  to change its mode so i could read it.
  

  
  afterwards, i used
  $bmpname = "pic.bmp";
  exec('cd /var/www/images/');
  exec('/usr/local/otb2sms -r -l 515 03 $bmpname > sample.txt' );
  

  
  the exec statement is not working.
  but when i type it in the server, it works. but why not on the php code?
  

  
  before, i used this and it worked. it was until the time that i used chmod when it started not working. does chmod has something to do why id didnt work?
