3-dimensional array

Newbie problem:  I'm having trouble retreiving all of the values from a
three-dimensional array ($bubs). The code that sets it up is below. I've
tried using three 'for' loops, but this
didn't work. 

Thanks,

Gavin

else {
 
      while (list($key,$val) = each($HTTP_POST_VARS)) {
         $dd = $day; 
         $mm = $month; 
         $yy = $year; 
         $dater = $dater1;
	 if (!ereg("aer_", $key) && !ereg("goal_", $key) && !ereg("Submit",
$key) && !ereg("day", $key) && !ereg("month", $key) && !ereg("year", $key)
&& !ereg("dater", $key)) {
            if (ereg("m([0-9+]+)e([0-9+]+)(_.*)", "$key", $ex_s)) {
                $ex_s[3] = ereg_replace("_", "", $ex_s[3]);
                $bubs[$ex_s[2]][$ex_s[1]][$ex_s[3]] = "$val";
            } 
         }
      }
}
