Wrapping boost::shared_ptr in PHP using SWIG

If I use SWIG to wrap this C++ function:

boost::shared_ptr<Client> Client::create() {
    return boost::shared_ptr<Client>(new Client());
}

And then call it in PHP:

$client = Client::create();
echo gettype($client);

The type of $client is resource, not object, and so I cannot call Client methods.

What are my options for wrapping this function? I'm creating a PHP wrapper for someone else's C++ library, so reworking the code to not use boost::shared_ptr isn't really an op开发者_Python百科tion.

This is the only solution I've come up with so far:

MyClient Client::createObject() {
    return *Client::create();
}

And calling it in PHP:

$client = Client::createObject();
echo gettype($client);

Now the type of $client is object and I can call Client methods on it. Is this a reasonable workaround? If not, what should I be doing?
