mysql_data_seek

(PHP 3, 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);
?>
