Array accessor

georgeshout

While parsing xml I get the array below... what is the syntax for accessing the [id].

I have tried the following...

$test = $search[0]['@attributes']['id']... ' i get null'
$test = $search[0][@attributes]['id']... ' Use of undefined constant attributes - assumed 'attributes' '
$test = $search[0]['id']... ' i get an array with the id value... however I want to avoid this.'

$search = array(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[id] => bk101
)

        [author] => Gambardella, Matthew

    )

Thanks... in advance

Not sure, but how about:

$search[0]->attributes['id']

This returned null....

The solution was to cast as a string...

$test = (string) $search[0]['id'] ... this produced the outcome I needed.

It seems weird to me though, since you never showed there being such an element in the array to begin with. But on the other hand, there might have been more in the array than you posted since the parentheses don't match up.

As for the simplexml, I'd have expected this to work

foreach($search[0]->attributes() as $att => $val)
	if ($att == 'id')
		$test = $val;
