  Hi Arun,

  The string and regular expression functions allow you to do things
  like this. See the PHP manual http://www.php.net/manual for more
  details.  Functions that are likely to be most useful are explode,
  split and preg_match.

  Be warned - the preg functions are challenging for users not familiar
  with regular expressions.


  Here is an example:

  $data  = pg_result ($result, 0, 0);
  $array = explode (' ', $data);

  // Print the second word in the array
  echo $array[1];

  // Print the first and third words in the array
  echo $array[0] . " " . $array[1];


Good Luck!
