This is just a quick and dirty template that I use to begin writing my apps. If you know of a better way to approach various portions of this code I would love to hear it. It\'s assuming you are using the latest PHP SDK and is positioned around Iframe based application (though it works with FBML, I would just use AJAX calls to request auth as it\\\\\\\'s a little more seamless).
