variable variable... right up there with array array
basically what you are saying is resolve $var, then find out what that variable
assume your $counter is currently at 5
$var = "v".$counter."_high_indiv";
would mean that $var= "v5_high_indiv"
assuming that v5_high_indiv is dynamically assigned somewhere as a variable
$$var is the value of $v5_high_indiv
variable variables are especially good in loops... for example, if you have
$user1, $user2, $user3....
to print out all the variables would require one line per variable (and alot of
typing). using variable variables you could print out the value of all users by
