А правильно выстроить цикл?

Автор вопроса: Егор

Имеется массив такого вида

Array
  (
      [0] => Array

              [C_SORT] => 1100
              [ACTIVE] => Y
          )

Хочу получить из него таблицу в каждой строке которой должно быть пять [ID] элементов:

<tr>417 418 420 421 422</tr>
<tr>423 424 425 426 427</tr>

Делаю я вот так:

<?
$array = array_chunk($arResult["QUESTIONS"]["q18"]["STRUCTURE"], 5, true); 
            foreach ($array as $key => $arAnswer)
            {
            ?>
            <tr> 
            
            <?print_r ($arAnswer["ID"]);?>
             
 
            </tr>
            <?
            } ?>

Но вот так ID не выводит, я так понимаю потому что сперва нужно указать что бы цикл проходил по ключам массива

Если сделать вывод без ID:

<?print_r ($arAnswer["ID"]);?>

То вот что выдает:

<tr>

)
             
            </tr>

То есть нужно как то указать что бы он брал именно ID у каждого элемента первого массива, а как это сделать не могу понять, пробовал добавить туда еще один цикл то там запутался еще больше

Если нужен "иной" вид - приведите пример как именно оно должно быть выведено:

$i = 1
echo "<tr>";
foreach ($array as $key => $arAnswer){
   echo "<td>$key</td>"; //<- возможно не то поле и тогда:
   //                      echo "<td>{$arAnswer['ID']}</td>"
   echo ($i%5==0?"</tr><tr>":"");
   $i++;
}
echo "</tr>";

Если начальным значением задать i=1 а не нулю как изначально было то всё начинает работать как нужно) Владимир, благодарю за помощь!

<?
$i = 1;
echo "<tr>";
foreach ($array as $key => $arAnswer){
echo "<td>{$arAnswer['ID']}</td>"; //<- возможно не то поле и тогда: //echo "<td>{$arAnswer['ID']}</td>"
echo ($i%5==0?"</tr><tr>":"");
$i++;
}
echo "</tr>"; ?>
