@james If you are keeping a tally for Continuum SDK requests, on that same client call, we had a Drupal team comment they would be interested in a SDK for PHP. When Jerry suggested Continuum Scripting Framework may meet his needs, his response was that he would prefer a solution the required no external dependencies. (edited)
Jerry's suggestion here is a good one; CSF really doesn't use many external dependencies, and most of them are included or installed automatically for the customer. We could provide a complete list if that would make them feel any better about it though.An SDK for PHP sounds like a good Ideas portal addition, though this is the first I'm personally hearing on a request for a native PHP SDK.
