Uncaught exception 'Exception' with message 'Serialization of 'SimpleXMLElement

Question

function deal_taobao_data($data){
    $data = serialize($data);
    $data = str_replace('O:16:"SimpleXMLElement"', 'a', $data);
    $arrstr = unserialize($data);
    return $arrstr;
}
这是我的代码
处理一段
SimpleXMLElement Object
(
    [item_cats] => SimpleXMLElement Object
        (
            [@attributes] => Array
                (
                    [list] => true
                )            [item_cat] => Array
                (                ……
            )
    )
)
将其转化为数组
本地测试可以，上传后报错误：
Fatal error: Uncaught exception 'Exception' with message 'Serialization 
of 'SimpleXMLElement' is not allowed' in /web/taobao.php:328
Stack trace:

有没有朋友知道这一问题根源的。

本地测试成功返回的代码(省略了一部分)：
Array
(
    [item_cats] => Array
        (
            [@attributes] => Array
                (
                    [list] => true

Answer 3

1、SimpleXMLElement 不可被序列化
Uncaught exception 'Exception' with message 'Serialization of 'SimpleXMLElement' is not allowed' 
2、即便是可以，由
echo serialize(array(1));
a:1:{i:0;i:1;}
也不是像你那样替换

Answer 4

自己解决了，换一个函数！
function deal_taobao_data($data){
$arrstrs=json_encode($data);
$arrstr=json_decode($arrstrs,true);
return $arrstr;
}
