Question

I’m trying to sum up all the values in this script below but not sure how to do it, I searched the net and found array_sum() but not sure where to use it…

  while($row = mysql_fetch_array($result))
  {
  $a = $row['aa'];
  $b = $row['bb'];
  $c = $row['cc'];
  }

in the script above, all the variables has a value of either 1 or 0, I can manually add them by using $a + $b + $c but if the list gets longer it will take some time. Is there a faster way so that i can add up everything?

illustration of table

  ID   NAME   AA   BB   CC
  1    YOU    1    0    1
  2    ME     1    1    1

So what i want is that “YOU” will have the value of 2 while “ME” will have the value of 3

Answer 1

SELECT (aa+bb+cc) AS yoursum FROM yourtable

According to your comment, I guess you want something like this:

SELECT SUM(aa), SUM(bb), SUM(cc) AS yoursum FROM yourtable

Or this, if there name column can have duplicates.

SELECT name, SUM(aa+bb+cc) AS yoursum 
FROM yourtable
GROUP BY name
