Question

所以，我想在HTML表格中打印以下三维数组。

array ( 'BTC_YACC' => array ( 0 => array ( 'orderNumber' => '3585379', 'type' => 'sell', 'rate' => '0.0001', 'amount' => '128', 'total' => '0.0128', 'date' => '2014-05-18 08:54:37', ), ), )

这就是我提出的:( OrderNumber = OrderID）。

$tableopenorders = "<table><th>OrderID</th><th>Type</th><th>Rate</th><th>Amount</th><th>Total in BTC</th><th>Date placed</th><tr>";

for($element = 0; $element < count($decodedopenorders); $element++) {
    $tableopenorders .= "<tr>";
    for($row = 0; $row < 1; $row++) {
        for ($col = 0; $col < 6; $col++) {
             $tableopenorders .= "<td>".$decodedopenorders[$element][$row][$col]."</td>";
        }   
    }
    $tableopenorders .= "</tr>";
}

$tableopenorders .= "</table>";

最多有＆＃34; count（$ decodingopenorders）＆＃34; $ elements，max。 $ decodingopenorders数组中有1行$ 6行和6行。迭代器开始为0，所以我使用了＆lt;。

为什么这不起作用？

当您遍历阵列时，您已将密钥更改为典型的0,1,2,3之外的其他内容。当您更改密钥时，$ decodingopenorders [0]不再有效，而是您必须调用$ decodedopenorders [ 'BTC_YACC'];所以这是我开始工作的代码：

$decodedopenorders = array ( 
    'BTC_YACC' => array ( 
                     0 => array ( 
                          'orderNumber' => '3585379', 
                          'type' => 'sell', 
                          'rate' => '0.0001', 
                          'amount' => '128', 
                          'total' => '0.0128', 
                          'date' => '2014-05-18 08:54:37') 
                      ) 
                      );
$tableopenorders = "<table><th>OrderID</th><th>Type</th><th>Rate</th><th>Amount</th><th>Total in BTC</th><th>Date placed</th><tr>";

foreach ($decodedopenorders as $element => $value) {
    $tableopenorders .= "<tr>";
    foreach ($decodedopenorders[$element] as $row => $value){
        foreach ($decodedopenorders[$element][$row] as $order) {
           $tableopenorders .= "<td>". $order ."</td>";
             }   
        }
    $tableopenorders .= "</tr>";
    }

    $tableopenorders .= "</table>";

    echo $tableopenorders;

PHP打印三维数组
