建立一个循环怎么样？

772

我有一个这样的数组

Array

      [10] => Array
          (
              [ID] => 427
              [FIELD_ID] => 79
              [QUESTION_ID] => 79

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

我想从它的每一行中获取一个表，其中应该有五个 [ID] 元素：

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

我这样做：

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

但这不是 ID 的显示方式，据我了解，因为首先您需要指定循环遍历数组的键

如果您在没有 ID 的情况下提款：

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

这就是它给出的：

<tr> 
            
            Array

也就是说，您需要以某种方式指定它将准确地从第一个数组的每个元素中获取 ID，但我不知道如何做到这一点，我试图在那里添加另一个循环，然后我更加困惑

如果您需要“不同”视图 - 请举例说明应如何显示：

$i = 1
echo "<tr>";
foreach ($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>";

如果您将初始值设置为 i=1 而不是原来的零，那么一切都会开始正常工作）弗拉基米尔，谢谢您的帮助！

<?
$i = 1;
echo "<tr>";
foreach ($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>"; ?>
