Php 如何循环对象内部的数组,php,Php,我是个初学者，所以请容忍我。我试图在表中显示JSON响应。我已经检索到了JSON数据，但是结构有点复杂，我需要遍历它来获取我想要显示的数据这是一个学校时间表，因此我选择的格式如下： Session | Monday | Tuesday | Wednesday ----------------------------------------------------------- Home Room | 2HRS - JS1.6 | 2HRS

我是个初学者，所以请容忍我。我试图在表中显示JSON响应。我已经检索到了JSON数据，但是结构有点复杂，我需要遍历它来获取我想要显示的数据

这是一个学校时间表，因此我选择的格式如下：

Session        | Monday        | Tuesday       | Wednesday
-----------------------------------------------------------
Home Room      | 2HRS - JS1.6  | 2HRS - JS1.6  | ....
08:30 - 08:45  | Homeroom      | Homeroom      | ....
               | Ms Jones      | Ms Jones      | ....
               |               |               | 
Period 1       | 2ENS - JS1.6  | 2ENS - JS1.6  | ....
08:45 - 09:35  | English       | English       | ....
               | Ms Jones      | Ms Jones      | ....

我要做的第一件事是在房间中循环，并将它们显示在一张桌子上

这是我的JSON响应的开始：

                "EndTime": "09:35"
            }
        }
    }
]}

这是我的一些代码

$response = json_decode($get_data, true);       
$rooms = $response['data']['0']['timetable'];

?>
<?php foreach ($rooms['1'] as $v) { ?>
<tr>
<td></td>
<td class="first"><?php echo $v;} ?></td>
</tr>

我可能在这里完全偏离了轨道，所以任何指导都将不胜感激

首先确保json验证并简化它

            "StartTime": "08:30",
            "EndTime": "08:45"
        },
        {
            "DayNumber": "3",
            "ClassCode": "2HRS",
            "ClassDescription": "Homeroom",

然后你可以做这样的事情

<?php
$get_data = file_get_contents('inf.json');

$response = json_decode($get_data, true);       
$rooms = $response['data']['0']['timetable'];
?>
<?php foreach ($rooms as $v) { 
    echo $v['DayNumber'];
    echo " ";
    echo $v['ClassCode'];
    echo " ";
    echo $v['ClassDescription'];
    echo $v['Room'];
    echo " ";
    echo $v['StaffNameExternal'];
    echo " ";
    echo $v['StaffTitle'];
    echo "<br>";
}
?>

您好，您能给我们举一个您希望最终结果如何的例子吗？我指的不是价值而是关键。嗨，基思。我用键而不是值更新了表。我希望这有帮助。谢谢。嗨，你能给我们举一个你希望最终结果如何的例子吗？我指的不是价值而是关键。嗨，基思。我用键而不是值更新了表。我希望这有帮助。谢谢，太棒了！谢谢你，大卫。但是，有几个问题，这完全是我的错，因为我没有包含完整的JSON响应。您遇到了什么问题吗？对不起，我无意中发布了我的评论。我在第一期文章中添加了第二次编辑。在第2个周期之后，有一个“休会期”，它不包含与其他周期相同的键/值。另一个问题是某些天有一个额外的周期。见编辑3。时段3有一个“第5A天”。这是因为学生们在交替的几周里会有不同的科目。我已经更新了编辑1中的表格，以反映格式，包括“第5A天”，如果它存在的话。我希望这是明智的，这太棒了！谢谢你，大卫。但是，有几个问题，这完全是我的错，因为我没有包含完整的JSON响应。您遇到了什么问题吗？对不起，我无意中发布了我的评论。我在第一期文章中添加了第二次编辑。在第2个周期之后，有一个“休会期”，它不包含与其他周期相同的键/值。另一个问题是某些天有一个额外的周期。见编辑3。时段3有一个“第5A天”。这是因为学生们在交替的几周里会有不同的科目。我已经更新了编辑1中的表格，以反映格式，包括“第5A天”，如果它存在的话。我希望这是有意义的，您只是回显值，而不是将值存储在表中。您只是回显值，而不是将值存储在表中。
