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
1 Hassan
2 Jack
3 Rose
---------------
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 — Set result pointer to a specified field offset
Description
bool mysql_field_seek
( resource $result
, int $field_offset
)
Seeks to the specified field offset. If the next call to mysql_fetch_field() doesn't include a field offset, the field offset specified in mysql_field_seek() will be returned.
Parameters
- result
-
The result resource that is being evaluated. This result comes from a call to mysql_query().
- field_offset
-
The numerical field offset. The field_offset starts at 0. If field_offset does not exist, an error of level E_WARNING is also issued.
Return Values
Returns TRUE on success or FALSE on failure.

<?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)
