Question

Trying to sum the total of a column and save as a variable.
The query has worked as I have tested it with PHPMyAdmin. Just struggling to save the figure received from the query into a variable.

 $con = mysql_connect(DB_HOST, DB_USER, DB_PASS);
 if (!$con)
   {
   die('Could not connect: ' . mysql_error());
   }

 mysql_select_db(DB_NAME, $con);

 $result = mysql_query("SELECT SUM(column_name) FROM tablename");



  mysql_close($con);  

Any help would be much appreciated.

Thanks!

Try this:

$result = mysql_query("SELECT SUM(column_name) as soma FROM tablename");

$row= mysql_fetch_array($result);

$sum= $row['soma'];
