mysql_field_name
I spent a good deal of time trying to get the example to work, but the example does not work.
To do what the exaple is trying to do, you would need to use mysql_data_seek
assume we have table named testing which contains
id name

Here is an expample that will do the above example.
Since I am more comfortable in a OOP setting, I used mysql_fetch_object
<?php
require("myConnenctionFile.php");
$sql="SELECT * from testing";
$result=mysql_query($sql);
$row = mysql_fetch_object($result);
echo $row->id . ' ' . $row->name; // Output is (1 Hassan)
mysql_data_seek($result,2);
$row = mysql_fetch_object($result);
echo $row->id . ' ' . $row->name; // Output is (3 Rose)
echo "<BR><BR>";
?>
mysql_field_seek
(PHP 4, PHP 5, PECL mysql:1.0)
mysql_field_seek — Устанавливает внутренний указатель поля на переданное смещение.
Описание
array mysql_field_seek
( resource $result
, int $field_offset
)
Перемещает указатель к колонке с переданным индексом. Если следующий вызов функции не содержит смещения, будет возвращено смещение, содержащееся в mysql_field_seek().
См. также mysql_fetch_field().

<?php
mysql_connect("sql.server.com", "username", "password") or die(mysql_error());
mysql_select_db("database") or die(mysql_error());
$sql="SELECT * from table1";
$result=mysql_query($sql);
$row = mysql_fetch_array($result);
echo $row['ID'] . ' ' . $row['Name']; // Output is (1 Hassan)
mysql_field_seek($result,2);
echo $row['ID'] . ' ' . $row['Name']; // Output is (3 Rose)
?>
---------------
// You can see that the seek command forwarded the pointer one step and skipped row number 2

A dumb comment... but it may save people some time :
mysql_field_seek != mysql_data_seek
In order to fetch again the results of a resource result from the beginning, you will use mysql_data_seek(id, 0)
