correction from the function below... this works better:

function randomselection($sql, $c) {
 $data = getdata($sql);
 $totalcount = count($data);
 $j = array();
 if($totalcount < $c) {//not enough data points
  return $data;
 }
 for($i = 0; $i < $c; $i++) {
  $j[$i] = mt_rand(0,$totalcount-1);
  $newdata[$i] = $data[$j[$i]];
  unset($data[$j[$i]]);
  sort($data);
  $totalcount--;
 }
 return $newdata;
}
