我正在使用 php 和 dropbox api 开发一个应用程序,并试图遍历一个多维数组并输出到一个表中。到目前为止,这是我的代码:

<?php
session_start();

# Include the Dropbox SDK libraries
require_once "Dropbox/autoload.php";
use \Dropbox as dbx;

// Create connection
$con = mysqli_connect(
    "localhost", "sintegra_aggre", "*******", "sintegra_aggregator"
);

// Check connection
if (mysqli_connect_errno($con)) {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

if (isset($_SESSION['uid'])) {
    $password = $_SESSION['pass'];
    $username = $_SESSION['user'];
    $email = mysqli_query($con, "
        SELECT * 
        FROM main_users
        WHERE
            password='$password'
            AND username='$username'
    ");

    if ($email >= 1) {
        // let them stay on page
    } else {
        header("Location: logout.php");
    }
} else {
    header("Location: login.php");
}

$accessToken = $_SESSION['accessToken'];

$dbxClient = new dbx\Client($accessToken, "PHP-Example/1.0");

$folderMetadata = $dbxClient->getMetadataWithChildren("/upload");

foreach ($folderMetadata as $value) {
    echo $value;
    foreach ($value as $val) {
        echo $val . "<br />";
    }
    echo "<br /><br />";
}
?>

这是数组 print_r 的输出:

我尝试了来自帖子的不同方法的组合,例如:

他们都没有工作。

我希望有人能给我一些代码,这些代码将遍历数组并将其输出到表中。也只是需要放入表格的内容数组

在此先感谢,马库斯

一点内联和块 php 将做基础。其余的格式由您决定;D

为了加快速度,所有 foreach 都使用值作为参考来完成。

修订答案

根据新信息,由于您希望将其与顶部的标题一起布置,因此您需要尝试以下操作:

<?php $headings = array_keys($array['contents'][0]); ?>

<table>
    <tr>
        <?php foreach( $headings as &$heading ): ?>
            <th><?php echo $heading; ?></th>
        <?php endforeach; ?>
    </tr>
    <?php foreach( $array['contents'] as &$file ): ?>
        <tr>
            <?php foreach( $file as &$data ): ?>
                <td><?php echo $data; ?></td>
            <?php endforeach; ?>
        </tr>
    <?php endforeach; ?>
</table>

第一行将 array_keys 作为标题,打印出标题行,然后通过引用直接从数组中遍历数据行。

以前的修订

这是我的最后一个答案,它在左侧显示带有标题的表格,数据显示在列中。

<?php
    $output = array();

    foreach( $test['contents'] as &$file )
    {
        foreach( $file as $heading => &$value )
        {
            $output[$heading][] = $value;
        }
    }
?>

<table>
    <?php foreach( $output as $heading => &$data): ?>
        <tr>
            <th><?php echo $heading; ?></th>
           <?php foreach( $data as &$value ): ?>
               <td><?php echo $value; ?></td>
           <?php endforeach; ?>
        </tr>
    <?php endforeach; ?>
</table>

由于表格的布局方式,您只需使用一点洗牌即可使数组正确迭代。不过,可能有上千种不同的方法来写这个。
