在PHP中循环遍历stdClass对象

Question

我有一个名为$result的数组，它包含查询结果。加载视图时，我将varible作为参数传递。我试图以Document_NoDescription数量访问这些值，并将它们显示给用户。

我已经尝试循环遍历数组，并不断地得到这个错误。不能使用stdClass类型的对象作为数组

值$result

)

代码试图访问其中的数据.

<?php  foreach ($result as $lines):
           ?>
            <?php $lineIndex=1;  $count=0; foreach ($lines as $line):

            ?>
      <?php //print_r($lines); exit;?> 
        <div id="lines" class="lines">
            <div id="line" class="line">
                <div class="row">
                <div class="form-group col-lg-2">
                        <input disabled id="description" class="form-control input-group-lg reg_name" type="text"name="quantityinStore[]" value=" <?php if(property_exists($lines[$count], 'Description'))echo $lines[$count]->Description?>" placeholder=""/>
                    </div>

预期结果

我希望这些值出现在字段中，但是我一直在获取以下错误消息:不能使用stdClass类型的对象作为数组。

您有一个对象数组。每个对象都有可引用的属性。

因此，对于数组$result，可以迭代数组。

foreach($result as $row) {}

然而，每一行都是一个对象；对象的属性被引用如下：$row->Document_No

因此，如果要使用字段Document_NoDescription Quantity打印表，可以这样做：

<?php
// do whatever to get $result

// php logic finished...
?>
<table>
  <tr>
    <th>Document_No</th>
    <th>Line_No</th>
    <th>Description</th>
    <th>Type</th>
    <th>Quantity</th>
  </tr>
  <?php foreach($result as $row): ?>
  <tr>
    <td><?= $row->Document_No ?></td>
    <td><?= $row->Line_No ?></td>
    <td><?= $row->Description?></td>
    <td><?= $row->Type ?></td>
    <td><?= $row->Quantity ?></td>
  </tr>
  <?php endforeach; ?>
</table>

对于一种形式，同样的想法也适用于：

<?php foreach($result as $index => $row): ?>
<input disabled id="description" class="form-control input-group-lg reg_name" name=“description[<?= $index ?>]” value=“<?= $row->Description?>” >


...
<?php endforeach; ?>
