How do I access this object property?

The data returned in a request is (JSON):

stdClass Object
(
[USD] => stdClass Object
    (
        [7d] => 23.3414

I’m calling:

json_decode(...);

And trying to access it via:

echo $json->USD->7d;

But that fails, because the variable name cannot start with an integer. Is there any syntax in PHP for accessing this?

Otherwise I would fix this by doing:

$set = (array) $json->USD;
echo $set['7d'];

Answer 1

This is working:

$name = '7bar';
$o->$name = 'foo';
echo $o->{'7bar'};

As you see in the example there are two different ways to access variables with uncommon names.
