The end result will be the same, but in the case of "$i", you're forcing the PHP interpreter to interpret the string "$i", looking for variables (like $i), and output whatever else is in the string (which in this case is nothing). Also, if $i is an integer, you have the same problem as above. In the first case, you get $array[7]. In the second case, you get $array['7']. Paul -- Paul M. Foster
