Twilio developer evangelist here.
Tpojka had the right answer, I just wanted to follow up so that other people that might see this can see the answer.
The key is that, as the documentation says:
The use keyword must be declared in the outermost scope of a file (the global scope) or inside namespace declarations. This is because the importing is done at compile time and not runtime, so it cannot be block scoped.
So, you want to update your controller code to look like this:
use Twilio\Jwt\AccessToken;
use Twilio\Jwt\Grants\VideoGrant;
use Twilio\Jwt\Grants\SyncGrant;
use Twilio\Jwt\Grants\IPMessagingGrant;
public function startRoom()
{
$TWILIO_ACCOUNT_SID = '';
$TWILIO_API_KEY = '';
$TWILIO_API_SECRET = '';
// and so on...
}
Hope this helps.
