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 die ("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);
?>
