在 PHP 中循环遍历 stdClass 对象

Question

我有一个名为 $result 的数组，其中包含查询结果。加载视图时，我将变量作为参数传递。我正在尝试访问 [Document_No] [Line_No][Description] [Type] [Quantity] [Unit_of_Measure] 中的值并将它们显示给用户。

我试图遍历数组并不断收到此错误。不能使用 stdClass 类型的对象作为数组

$result 的值

Array

(

    [0] => stdClass Object

        (

            [Key] => 40;3P4RAwJ7/0kATQBQAC0AMAAwADAAMgAAAACHIE4=7;38242640;

我希望这些值出现在字段上，但我不断收到此错误消息无法使用 stdClass 类型的对象作为数组

Answer 1

无需使用此循环foreach ($lines as $line)。你可以直接使用$lines->Description

Answer 2

你有一个对象数组。每个对象都有可以引用的属性。因此，对于数组$result，您可以遍历数组。foreach($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，如果您想使用字段 [Document_No] [Line_No][Description] [Type] [Quantity] 打印表格，您可以这样做：<?php// do whatever to get $result// php logic finished...?><table>&nbsp; <tr>&nbsp; &nbsp; <th>Document_No</th>&nbsp; &nbsp; <th>Line_No</th>&nbsp; &nbsp; <th>Description</th>&nbsp; &nbsp; <th>Type</th>&nbsp; &nbsp; <th>Quantity</th>&nbsp; </tr>&nbsp; <?php foreach($result as $row): ?>&nbsp; <tr>&nbsp; &nbsp; <td><?= $row->Document_No ?></td>&nbsp; &nbsp; <td><?= $row->Line_No ?></td>&nbsp; &nbsp; <td><?= $row->Description?></td>&nbsp; &nbsp; <td><?= $row->Type ?></td>&nbsp; &nbsp; <td><?= $row->Quantity ?></td>&nbsp; </tr>&nbsp; <?php endforeach; ?></table>对于表单，同样的想法适用：<?php foreach($result as $index => $row): ?><input disabled id="description" class="form-control input-group-lg reg_name" name=“description[<?= $index ?>]” value=“<?= $row->Description?>” >...<?php endforeach; ?>
