遍历多维数组

Question

I am developing an application using php and the dropbox api and am trying to loop through a multidimensional array and output to a table. 我正在使用php和dropbox api开发应用程序，并试图遍历多维数组并输出到表。 This is my code so far: 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 />";
}
?>

and this is the output from the print_r of the array: 这是数组的print_r的输出：

I have tried a combination of different methods from posts such as: 我尝试了多种不同方法的组合，例如：

and none of them have worked. 他们都没有工作。

I was hoping someone would be able to give me a bit of code that will loop through the array and output it into a table. 我希望有人能够给我一些代码，这些代码将遍历数组并将其输出到表中。 It is also only the contents array that needs to be put into the table 也是只需要将内容数组放入表中

Thanks in advance, Marcus 预先感谢，马库斯

Answer 1

A little bit of inline and block php will do the basics. 内联和阻止php的一点点就可以了。 The rest of the formatting is up to you ;D 其余的格式化取决于您； D

All foreach have been done with the values as references in an effort to speed things up. 所有的foreach都已将这些值作为参考来完成，以加快速度。

Revised Answer 修改后的答案

Based on new information, since you want it laid out with the headings at the top you'd want to try something like this: 根据新信息，由于您希望将其布置在顶部，因此请尝试执行以下操作：

<?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>

First line grabs the array_keys as headings, prints out the heading rows and then goes through the data rows directly from the array by reference. 第一行将array_keys用作标题，打印出标题行，然后通过引用直接从数组中浏览数据行。

Previous Revision 以前的修订

This was my last answer, it displays the table with the headings on the left, with the data displayed in columns. 这是我的最后一个答案，它显示带有左侧标题的表格，并在列中显示数据。

<?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>

Because of the way tables are laid out, you can just use a little bit of shuffling to get an array to iterate correctly. 由于表的布局方式，您可以使用一些改组就可以正确地迭代数组。 There's probably a good thousand different ways to write this though. 不过，可能有成千上万种不同的方式来编写此代码。
