问题
Is there any way to embed a Google+ hangout app in a PHP-based website? Can I load the app inside an iframe without having to land on Google+ hangout page? If so, how?
回答1:
Not really. Launching a Hangout Video Call from your own website is possible, but without special coordination with Google, it will open it in its own window/tab.
See http://www.youtube.com/watch?v=Al4SbeVyLm4 for further information about how to start a Hangout Video Call from your own website.

After doing some research I found out that we can not embed a Google+ Hangout in our application. We can only do that inside a Google+ hangout page. There's an active issue tracker opened on code.google.com where you can vote up and comment so that Google can release this feature in the coming API releases.
