Re: how to combine the results of two variables to echo another variable?

There is no need for variable variables at all. Use arrays for stuff like this. Yeah, v-vars are indeed powerfull, powerfull to lead ppl to unpredictable clutter up the root of the namespace and write ugly code -- like demonstrated below in all beauty.

Variable variables are one of the most powerfull features of php I've found. Very usefull when you dont know how many variables to be processed in a form for e.g.

for( $i=1; $i <= $num_fields; $i++) {
      $blah = "field_" . $i;
      // $blah is now "field_1" first time through the loop

      $blah = $$blah;
      // now $blah holds what was input into the appropriate input
}
