mysql_data_seek

Description

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.

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); ?>
