We've been seeing a lot of PHP development on our APIs, and we're hopeful that the developers using that language will continue to add shared resources. With that in mind, Jason Johnston from our team wrote up this "uber basic" client: https://github.com/jhnstn/nb-php

And Ryan Morgan from Veracity Media added body support for POST/PUTing to this OAuth 2.0 wrapper: https://github.com/RyanMorgan/PHP-OAuth2

Note: These are resources provided on an as-is basis and are not supported by NationBuilder. We encourage developers to continue to add to them and to use GitHub's pull request and issue reporting features.
