Do bazy danych pola SET dodaje zaznaczone checkboxy. nie ma problemu jesli 
jest ich w sumie do 32 (ja mam 38), potem zaczynaja sie schody. Dlaczego 
zaznaczajac checkboxa po numerze 32 porownanie array_sum($_POST['table'] & 
$in nie odzanacza go? Przed 32 nie ma zadnego problemu...

$in = 1;
for($i=1;$i<=38;$i++) {
echo '<input type="checkbox" name="table[]" 
value="'.$in.'"'.(array_sum($_POST['table'] & $in?' checked':'').'><label 
for="table'.$i.'">'.$formularz['wartosc'][$i-1].'</label>';
  $in = $in * 2;}

kiedy wyswietlam
$in = 1;
for($i=1;$i<=64;$i++)
{
echo $i.' '.$in.'<br>';
$in = $in * 2;
}

39. 274877906944
40. 549755813888
41. 1.09951162778E+12
42. 2.19902325555E+12
