PHP 'json_decode' 仅适用于第一项
[英] PHP 'json_decode' Working for First Item Only
本文介绍了PHP 'json_decode' 仅适用于第一项的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在解码 JSON 格式，我的 API 端点是 https://api.reliableserver.host/api/recent_activities(无身份验证)
我已经设法像这样显示第一项的值:
<tr class="css-xlbdcw"><td style="width: unset;最大宽度:未设置；填充:5px 20px；文本对齐:左;>><div class="vx_text-body-md";样式=颜色:RGB(44、46、47)；填充顶部:7px；padding-bottom: 7px;"><div角色=按钮"><?php echo $obj2['data'][0]['activity_date'];?>
</td><td style="width: unset;最大宽度:未设置；填充:5px 20px；文本对齐:左;>><div data-testid="verticalList"><a tabindex=0"href=/activity/payment/87J62844XL761054H">
</td><td style="width: unset;最大宽度:未设置；填充:5px 20px；文本对齐:右;><div class="vx_text-body-md";样式=颜色:RGB(44、46、47)；填充顶部:7px；padding-bottom: 7px;"><div role="button"><?php echo $obj2['data'][0]['activity_amount'];?></div>
</td></tr>
这适用于第一个项目，我如何使用 foreach 让它通过每个项目 - 我试过但无法让它工作.
谢谢
解决方案
如果您希望自己灵活地呈现项目，可以使用过滤器数组 ($filter)，如下所示:
';//打开一行foreach ($record as $key => $item) {if (in_array($key, $filter)) {//只显示过滤的项目回声<<<<div角色=按钮">$item
</td>赫里多克；}}回声'</tr>';//关闭行}
我们使用 HEREDOC 因为它允许我们优雅地使用注入的变量(例如 $item)渲染 HTML.
I'm decoding JSON format, my API Endpoint is https://api.reliableserver.host/api/recent_activities (No Auth)
I've already managed to display the values of the first item like this:
<?php
$url2 = "https://api.reliableserver.host/api/recent_activities";
$obj2 = json_decode(file_get_contents($url2), true);
?>
<tr class="css-xlbdcw">
<td style="width: unset; max-width: unset; padding: 5px 20px; text-align: left;">
<div class="vx_text-body-md" style="color: rgb(44, 46, 47); padding-top: 7px; padding-bottom: 7px;">
<div role="button">
<?php echo $obj2['data'][0]['activity_date']; ?>
</div>
</div>
</td>
<td style="width: unset; max-width: unset; padding: 5px 20px; text-align: left;">
<div data-testid="verticalList">
<a tabindex="0" href="/activity/payment/87J62844XL761054H"><?php echo $obj2['data'][0]['activity_title']; ?></a>
<div style="color: rgb(44, 46, 47); font-size: 11px;"><?php echo $obj2['data'][0]['activity_status']; ?></div>
</div>
</td>
<td style="width: unset; max-width: unset; padding: 5px 20px; text-align: right;">
<div class="vx_text-body-md" style="color: rgb(44, 46, 47); padding-top: 7px; padding-bottom: 7px;">
<div role="button"><?php echo $obj2['data'][0]['activity_amount']; ?></div>
</div>
</td>
</tr>
This is working for the first item, how do i make it go through each item using foreach - I tried but couldn't get it working.
Thanks
解决方案
If you wanted to allow yourself flexibility in rendering items, you could use a filter array ($filter), as follows:
<?php
$response = file_get_contents('https://api.reliableserver.host/api/recent_activities');
$response = json_decode($response, true);
$filter = ['id', 'activity_amount']; // select which items to show
foreach ($response['data'] as $record) {
echo '<tr class="css-xlbdcw">'; // open row
foreach ($record as $key => $item) {
if (in_array($key, $filter)) { // show filtered items only
echo <<<HEREDOC
<td style="width: unset; max-width: unset; padding: 5px 20px; text-align: left;">
<div class="vx_text-body-md" style="color: rgb(44, 46, 47); padding-top: 7px; padding-bottom: 7px;">
<div role="button">
$item
</div>
</div>
</td>
HEREDOC;
}
}
echo '</tr>'; // close row
}
We use HEREDOC as it allows us to elegantly render HTML with variable(s) (e.g. $item) injected.
