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!
