space increment

Hi all, I would like to have codes which will could automatically generate as many as sequence number variables based on how many rows return from the query, such as if I have 10 rows from the query result, I would have $var1,$var2,$var3,$var4....and so on, but the value of $var1 would equal to 3 spaces, and value of $var2 would equal to 6 spaces, then $var3 would equal to 9 spaces and so on. Could anyone tell me how could I write codes for this purpose. Thank you very much in advance! Calvin Chua
