是否可以使用PHP更改SimpleXMLElement对象内的数据类型？

Question

I have this object

$data = simplexml_load_string('<xml><admin>0</admin></xml>');

where $data->admin = "0" (string). So with a string 0, the following would always return true

if($data->admin) {
    echo 'is admin';
}

By casting the variable, this would work correctly

if((int)$data->admin) {
    echo 'is admin';
}

But I'm still wondering if it's possible to change the data type inside the object (like doing so inside an array) so I don't have to do type casting.

Not with SimpleXML. What you can do is use DOMDocument instead. Using SimpleXML isn't recommended.
