Simplexml Problem

[selenin]

Hi I want the icon of a digg user

 

$apicall = 'http://services.digg.com/2.0/user.getInfo?usernames='.$username.'&type=xml';

    $result = simplexml_load_file($apicall);

      print_r($result);

 

With that code I'll get this:

 

            SimpleXMLElement Object

(

    [count] => 1

    [users] => SimpleXMLElement Object

        (

            [Ericquits] => SimpleXMLElement Object

                (

                    [username] => Ericquits

                    [about] => SimpleXMLElement Object

        )

 

    [version] => 2.0

    [authorized] => 0

    [data] => users

    [method] => user.getInfo

    [user] => None

 

So I want the icon the profile image of the user and I make this:

 

print (string)$result->users->Ericquits->icon;

 

This works, but my question is if there is a solution to get the icon without Ericquits the username? Because if write it little I don't get the icon...

[selenin]

nobody I really don't get it

[The Little Guy]

$username = "Ericquits";
echo $result->users->$username->icon;

Thanks a lot that works, I have to do it like that
