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!
