[php]Invalid argument supplied for foreach() Opcje

[Duke Nukem]

Witam!
Wyskakuje mi taki blad:
Invalid argument supplied for foreach() i wskazuje on linie na ten kod:

Kod

foreach ($arrVotes[$i] as $intVote)
        {
            if ($intVote && $arrSumvotes[$i])
            {
                $arrPercentvotes[$i][$j] = ($intVote / $arrSumvotes[$i]) * 100;
                $arrPercentvotes[$i][$j] = round($arrPercentvotes[$i][$j]);
            }
                else
            {
                $arrPercentvotes[$i][$j] = 0;
            }
            $j++;
        }

Co jest zle? Czemu to nie dziala?

[nospor]

to znaczy ze $arrVotes[$i] nie jest tablicą.

i prosze nie duplikowac tematow

[Duke Nukem]

$arrVotes jest tablica
no bo jest tak: $arrVotes = array(array());
Co poczac? Jakies inne pomysly? Czy to moze miec zwiazek z wersja php?

[nospor]

no wlasnie: $arrVotes = array(array());
to oznacza, ze $arrVotes[0] jest tablicą;
ale juz $arrVotes[$i] nie jest tablicą, gdyż $i to na przyklad 1

[Duke Nukem]

czyli wystarczy zmienic $arrVotes = array(array()); na $arrVotes = array();??

[nospor]

a zamien, wtedy cala logike twojego skryptu szlag trafi...
sluchaj, to ty powinienes wiedziec co chciales osiągnąc a nie ja. a jesli nie wiesz to pokaz wiekszy kawalek kodu, to moze cos sie wymysli
