Reading XML and storing to arrays in PHP

Question

I have this:

$xml = simplexml_load_file('test.xml');
print"<pre>";
print_r($xml);

It printout this:

SimpleXMLElement Object
(
    [b] => SimpleXMLElement Object
        (
            [c] => SimpleXMLElement Object
                (
                    [d] => 543
                )

        )

)

but when I type echo $xml["b"]["c"]["d"]; nothing happens

if you are using PHP5, I suggest you use OO approach of SimpleXML — Raptor

the print_r is kind of misleading,
actually the $xml is series/array of SimpleXmlElement objects

so

echo (int)$xml->b->c->d;  --- type casting is required

here is some reference you should take a look first

Additional to type casting,
because everything node inside the xml object is either string or int

PHP will auto convert for numeric string to integer,
however, is clearer if you provide the type hinting

var_dump($xml); --- you should see more information on the data type

Try echo $xml->b->c->d;

$xml is not array they are objects.
