我正在制作一个 Dropbox 文件浏览器来练习使用 API 并遇到了问题。这是我的代码:
<?php
$fileMetadata = $dbxClient->getMetadataWithChildren("/upload");
$headings = array_keys($fileMetadata['contents'][0]);
?>
<br /><br /><br />
<table border="2" class="table table-striped table-bordered table-hover">
<tr>
<?php foreach( $headings as &$heading ): ?>
<th><?php echo $heading; ?></th>
<?php endforeach; ?>
</tr>
<?php foreach( $fileMetadata['contents'] as &$file ): ?>
<tr>
<?php foreach( $file as &$data ): ?>
<td><?php echo $data; ?></td>
<?php endforeach; ?>
</tr>
<?php endforeach; ?>
</table>
我想删掉一些不需要的列,例如 rev、thumb_exists 等...
这是数组的 print_r:

请你告诉我如何从表中删除某些列或从数组中删除这些部分。
谢谢,马库斯
