# mysql_data_seek

(PHP 3 <= 3.0.18, PHP 4 >= 4.0.0)

mysql_data_seek -- Move internal result pointer

## Description

``bool mysql_data_seek` (resource result_identifier, int row_number)`

Returns `TRUE` on success, `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.

Example 1. MySQL data seek example
    &<?php
        $link = mysql_pconnect("kron", "jutta", "geheim")
            or die("Could not connect");

        mysql_select_db("samp_db")
            or exit("Could not select database");

        $query = "SELECT last_name, first_name FROM friends";
        $result = mysql_query($query)
            or die("Query failed");

        // 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\n";
                continue;
            }

            if(!($row = mysql_fetch_object($result)))
                continue;

            echo "$row->last_name $row->first_name<br />\n";
        }

        mysql_free_result($result);
    ?>
