How to plus value in MYSQL?

Question

PHP

Flew out of my head, how to correctly add to the current value of the mysql cell?

$info_id = mysqli_fetch_assoc(mysqli_query($link,"SELECT * FROM `clan_player` WHERE user_id = '".$message."'LIMIT 1"));
$querys = mysqli_query($link,"UPDATE clan_player SET  `rank = '".($info_id['rank']+1)."' WHERE user_id = '".$message."'");

Answer 1

mysqli_query($link, "UPDATE `clan_player` SET `rank`=`rank`+1 WHERE `user_id`='{$message}'");
