从对象中获取纯值

Anyone know how could i get the pure value out of this kind of object:

SimpleXMLElement Object
(
    [0] => 13863
)

Not matter what i did, i can not get the pure value from this object. Any advise would be helpful.

apply type casting like (int) $xml->your_node_name

Try this:

$value = $object->{0}

Curly braces are often useful for accessing awkwardly-named properties on objects, particularly in the context of XML.
