PHP Echo array values loop (no data displayed)

我有一个数组…下面是结构/data:

array(1) { 
    [0]=> object(SimpleXMLElement)#1 (18) 
        { 
            ["data_123"]=> object(SimpleXMLElement)#3 (29) 
            { 
                ["field1"]=> string(7) "123" 
                ["field2"]=> string(2) "10" 
                ["field3"]=> string(19) "2013-03-05 17:00:00" 
                ["field4"]=> string(19) "2013-03-05 18:00:00" 
            } 
                ["data_234"]=> object(SimpleXMLElement)#4 (29) 
            { 
                ["field1"]=> string(7) "234" 
                ["field2"]=> string(2) "10" 
                ["field3"]=> string(19) "2013-03-05 17:40:00" 
                ["field4"]=> string(19) "2013-03-05 18:10:00" 
            } 
        } 
    }

我正在尝试创建一个循环来显示数据，但没有显示:

foreach ($result as $key => $list) {
   echo "key.: " . $key . "'n";
   echo "field1: " . $list['field1'] . "'n";
   echo "field2: " . $list['field2'] . "'n";
}

只是没有返回任何数据。

我猜循环可能是错误的这个数组结构?

我如何得到这个数组的数据回显?

$list是对象的数组，因此需要两个循环和适当的语法。例如:

foreach($list as $objects) {
    foreach($objects as $key => $obj) {
        echo "key.: " . $key . "'n";
        echo $obj->field1 . "'n";
        echo $obj->field2 . "'n";
        echo $obj->field3 . "'n";
        echo $obj->field4 . "'n";
    }
}
