                                mysql_data_seek

   (PHP 3, PHP 4 )
   mysql_data_seek -- Move internal result pointer

Description

   bool mysql_data_seek ( resource result_identifier, int row_number)

   Returns TRUE on success or FALSE on failure.

   mysql_data_seek() moves the internal row pointer of the MySQL result
   associated with the specified result identifier to point to the
   specified row number. The next call to mysql_fetch_row() would return
   that row.

   Row_number starts at 0. The row_number should be a value in the range
   from 0 to mysql_num_rows - 1.

     Note: The function mysql_data_seek() can be used in conjunction
     only with mysql_query(), not with mysql_unbuffered_query().

   Example 1. mysql_data_seek() example
   <?php
       $link = mysql_pconnect("localhost", "mysql_user",
   "mysql_password")
           or die("Could not connect: " . mysql_error());
       mysql_select_db("samp_db")
           or die("Could not select database: " . mysql_error());
       $query = "SELECT last_name, first_name FROM friends";
       $result = mysql_query($query)
           or die("Query failed: " . mysql_error());
       /* fetch rows in reverse order */
       for ($i = mysql_num_rows($result) - 1; $i >= 0; $i--) {
           if (!mysql_data_seek($result, $i)) {
               echo "Cannot seek to row $i: " . mysql_error() . "\n";
               continue;
           }
           if (!($row = mysql_fetch_object($result)))
               continue;
           echo "$row->last_name $row->first_name<br />\n";
       }
       mysql_free_result($result);
   ?>
