also

if($poland["tagid"] == 1) {     $toparray[0] ++; } if($poland["tagid"] == 2) {     $toparray[1] ++; } if($poland["tagid"] == 3) {     $toparray[2] ++; } if($poland["tagid"] == 4) {     $toparray[3] ++; }

===

if ($poland["tagid"] >= 1 && $poland["tagid"] <= 4)     $toparray[$poland["tagid"] - 1]++;
