Question

好的，看看这个伏都教：

此代码：

$xml = new SimpleXMLElement($xml);
 $var = $xml->QBXMLMsgsRs->ClassQueryRs;
 $vars = print_r($var,true);

返回：

    SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [requestID] => Q2xhc3NRdWVyeXw1
            [statusCode] => 0
            [statusSeverity] => Info
            [statusMessage] => Status OK
        )

    [ClassRet] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [ListID] => 80000002-1241128424
                    [TimeCreated] => 2009-04-30T17:53:44-05:00
                    [TimeModified] => 2009-04-30T17:53:44-05:00
                    [EditSequence] => 1241128424
                    [Name] => D1
                    [FullName] => D1
                    [IsActive] => true
                    [Sublevel] => 0
                )

            [1] => SimpleXMLElement Object
                (
                    [ListID] => 80000001-1241128320
                    [TimeCreated] => 2009-04-30T17:52:00-05:00
                    [TimeModified] => 2009-04-30T17:52:00-05:00
                    [EditSequence] => 1241128320
                    [Name] => K1
                    [FullName] => K1
                    [IsActive] => true
                    [Sublevel] => 0
                )

            [2] => SimpleXMLElement Object
                (
                    [ListID] => 80000003-1241128452
                    [TimeCreated] => 2009-04-30T17:54:12-05:00
                    [TimeModified] => 2009-04-30T17:54:12-05:00
                    [EditSequence] => 1241128452
                    [Name] => S1
                    [FullName] => S1
                    [IsActive] => true
                    [Sublevel] => 0
                )
        )

)

但是，这段代码：

$xml = new SimpleXMLElement($xml);
 $var = $xml->QBXMLMsgsRs->ClassQueryRs->ClassRet;
 $vars = print_r($var,true);

返回：

SimpleXMLElement Object
(
    [ListID] => 80000002-1241128424
    [TimeCreated] => 2009-04-30T17:53:44-05:00
    [TimeModified] => 2009-04-30T17:53:44-05:00
    [EditSequence] => 1241128424
    [Name] => D1
    [FullName] => D1
    [IsActive] => true
    [Sublevel] => 0
)

对于我的生活，我无法访问这个对象的其余部分！ Echo，print_r ....如果我尝试访问特定变量，它就会消失！

PHP的SimpleXml是一个实现ArrayAccess接口的对象，这意味着您可以使用数组样式语法引用元素。

PHP SimpleXML既是Object又是Array？不可思议！
