Repeating table sum in PHP

I have 2 columns in a table called Points. 2 columns are UserPoints and UserID.

I want to be able to repeat the total number of points that the user has.

I have something like this, but I don’t think it is right.

$getTotalPoints = mysql_query("SELECT SUM(UserPoints) FROM `Points` WHERE `UserID` = '1'") or die(mysql_error()); 
$totalPoints = mysql_fetch_array($getTotalPoints);

When I repeat the previous statement, repeating "$ totalPoints", I get an "Array".

Does anyone know the correct query for this?

The result line is an array with as many elements as you got in SELECT. In your case, you have only 1 element (amount). Therefore, you should: echo $totalPoints[0]; If you need to debug such problems, I recommend that you read about the print_r function.
