lets say Ive got a while loop incrementing the value of $i and checking for the value of the variable named: $variable$i (such as $variable1, $variable2, $variable3). I'm testing if(isset()) on that variable this way: if(isset("$variable".$i)) and obviously, its not working. I know I must use eval to get this thing working, but I just don't know how to do it!
