Getting value from a SimpleXMLElement object

问题

I have

$number[0] 

which is a object(SimpleXMLElement) type.

It has just one element.

The element has this pair 0 -- 9

9 is a string I need to have in a variable.

回答1:

If you want to access anything in your SimpleXMLElement, you will have to access it like an object. i.e

$value = $xml->foo->bar->baz;

This is desribed in more detail at the official documentation for SimpleXML
