Mysql function Advanced skills in PHP programming - using Mysql function

Although PHP provides us with many functions, some things are still not very convenient to deal with. For example, the date and time functions provided by PHP are very limited. Mysql provides us with many such functions. Can I use Mysql functions to process PHP programs? 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.
