Avoid PHP notice when the "signed_request" is not well formatted. #11
Sorry it took this long to respond to this. At this time, there are merge conflicts, and I have a question: Is there a better or more comprehensive way to validate the signed_request? What are the scenarios where signed_request is modified or empty causing it to log a notice? If you want to update the PR and re-open this, we can look into this further. Thanks for your contribution.
