How do i manage an int field to add and subtract from the current value in php and a database system?

The Original Question for this mentioned Point Systems in which the person wanted to reward Points to people that post. Points are the example I'll be using in this answer. I'm going to use #DATABASE SELECT{ and #DATABASE SELECT } to signify the beginnings and end of your Select query. #DATABASE UPDATE points for an Update query. I'm going to assume that the field is points and points is an INT(7) at least on the User table. Firstly the only unfamiliar function I'm going to use is (int). This simply converts a string to an Integer and is good practice to use. $point_opperation = 1; #1 for add, 2 for subtract $point_amount = 1; #The points you want to change. #DATABASE SELECT { (user table) $current_points = (int)$DATABASE['points']; $point_amount = (int)$point_amount; $vaild = false; If($point_opperation true){ $DATABASE UPDATE user table, change points to $newpoint_amount } #DATABASE SELECT } (user table) Simply change $point_opperation (use comment to understand the two options) and $point_amount to change the amount to change. Currently it'll add one point. Change the DATABASE SELECT and the UPDATE as Applicable.
