iis php mysql PHP Mysql advanced skills in programming

The author made the following attempts.
$data_time="1998-12-31 23:59:59";
$c
$query_id=mysql_query("SELECT DATE_ADD(' $data_time',INTERVAL 1 YEAR)", $connect_id);
$data_time=mysql_result( $query_id,0);
mysql_close( $connect_id);
echo $data_time;
?>
By analogy, we can also use other functions provided by Mysql during the programming process.
Of course, please check the manual for the functions provided by Mysql and their usage.
Please correct me if I feel inappropriate!
