Foreach在功能上

Question

I got a question that hopefully is easy to answer.

In the function below the part "foreach($daten as $row)" is ignored in the second turn. Can somebody tell me, why the function acts that way?

I already tried to delete the "break"... no success.

function verweis_show($string,$art,$daten){


$ausgang = preg_split("/\[-\[(.*?)\/(.*?)\/(.*?)\]-\]/", $string,0,PREG_SPLIT_DELIM_CAPTURE);

$n = 0;

foreach($ausgang as $teil)
{
    $n++;

    if($n == 1)
    {
        $ergebnis .= $teil;

    }
    elseif($n == 2)
    {
        $stat_id = $teil;

    }
    elseif($n == 3)
    {
        $rel_id = $teil;

        if ($art != "old")
        {
            $z = 0;

            // wird im zweiten durchlauf seltsamerweise nicht noch einmal durchlaufen
            foreach($daten as $row) 
            { 
                $z++;

                if ($row['id'] == $stat_id)
                {
                    $rel_id = $z; 
                    break;
                }

            }
        }
    }
    elseif($n == 4)
    {
        $ergebnis .= "<div contenteditable='false' id='text_$stat_id' class='$teil' tabindex='-1'>$rel_id</div>";
        $n = 0;
    }
}

return $ergebnis;    

}

Answer 1

Foreach requires that it either has an array, or an object that has the traversable interface implemented, which PDOStatement probably does not.
