通過多維數組循環

Question

我正在開發一個應用程序使用PHP和Dropbox API，並試圖通過多維數組循環並輸出到表。這是到目前爲止我的代碼：

<?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 />"; 
} 
?> 

，這是從所述陣列的所述的print_r輸出：

我試圖從帖子例如不同方法的組合：

• Trouble Looping through multidimensional array
• PHP foreach loop through multidimensional array
• PHP foreach loop through multidimensional array
• PHP: Loop Through Multidimensional Array

和他們都沒有工作。

我希望有人能夠給我一些代碼，將通過數組循環並輸出到表中。它也是唯一的內容陣列，需要提前放入表

謝謝，馬庫斯

Answer 1

行內和塊的PHP的點點會做的基本知識。格式的其餘部分取決於你; D

所有的foreach已經完成了值作爲參考，以加快速度。

修訂答

基於新的信息，因爲你希望它奠定了在頂部的標題你會想嘗試這樣的：

<?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> 

第一行抓起array_keys作爲標題，打印標題行，然後通過引用直接從數組遍歷數據行。

以前的版本

這是我最後的答案，它會顯示在左側的標題，與在列中顯示的數據表。

<?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> 

由於佈局表的方式，您可以使用一點點混洗來獲得一個數組，以正確地進行迭代。可能有好幾千種不同的方法來編寫它。
