// Act 1 - Operations that don't require login
//
// First, we get a client-token.

try
{
  // this is optional to call explicitly
  // resource calls will automatically call this
  // if there's no access token claimed yet.
  $sceneID->GetClientCredentialsToken();

  // We got it, now we can query at will
  $result = $sceneID->User(1);

/////////////////////////////////////////////////
// if we want to invalidate the previous token
// we can call Reset()
$sceneID->Reset();

/////////////////////////////////////////////////
// Act 2 - Operations that do require a user
//
// This is a bit trickier
// First, we redirect to the SceneID login page

$sceneID->PerformAuthRedirect();

// After that, on the redirect page, we process
// the response sent by SceneID

try
{
  $sceneID->ProcessAuthResponse();
  // Note: this only needs to be done once, the tokens are stored in sessions

  // We can now identify the user by their login
  $result = $sceneID->Me();
