的var_dump

Question

我的DB返回一个包含数组的对象数组。

的var_dump

array (size=2)
  0 => 
    object(stdClass)[22]
      public 'customer_id' => string '10' (length=2)
      public 'cart' => string 'a:1:{s:32:"f9bb1d342b1c2a0bfe982ef405369ec0";a:9:{s:5:"rowid";s:32:"f9bb1d342b1c2a0bfe982ef405369ec0";s:2:"id";s:9:"101_30524";s:3:"qty";s:1:"1";s:5:"price";s:5:"104.5";s:4:"name";s:13:"Business Card";s:5:"image";s:18:"business-cards.gif";s:4:"ship";a:3:{s:6:"Ground";d:9.730000000000000426325641456060111522674560546875;s:11:"2nd Day Air";d:18.53999999999999914734871708787977695465087890625;s:9:"Overnight";d:26.269999999999999573674358543939888477325439453125;}s:7:"options";a:2:{s:17:"Print Description";s:16'...

注意cart是一个多维数组。如何遍历这些对象和数组并创建表？

<?php foreach($all_orders as $key => $val) : ?>

    <?php echo $key; ?>  <?php echo $val; ?>

<?php endforeach; ?>

这会导致以下错误：遇到PHP错误严重性：4096消息：类stdClass的对象无法转换为字符串

Answer 1

你可以尝试

echo "<pre>";
foreach ( $cart as  $all_orders ) {
    foreach ( $all_orders as $key => $value ) {
        echo $key, " = ", $value, PHP_EOL;
    }
}

Answer 2

使用stdClass运算符访问->对象的属性：

<?php foreach($all_orders as $key => $val) : ?>
Customer ID <?php echo $val->customer_id ?> has a total of <?php echo $val->order_total ?><br />
<?php endforeach ?>

Answer 3

PHP 5允许使用foreach循环遍历对象的 public 属性。

有关详细信息（和代码示例）：http://php.net/manual/en/language.oop5.iterations.php

Answer 4

我在MVC中使用PHP的ArrayObject：
us3.php.net/manual/en/class.arrayobject.php

        $arrayobject = new ArrayObject($dataRows);
        for ($iterator = $arrayobject->getIterator(); $iterator->valid(); $iterator->next()) {

        }

如何在对象/数组上循环foreach
