Your catch block is dumping the stack trace, which tells you *where* the error occurred, but it doesn't tell you *which* error occurred.
Add the following to your catch-block to determine the actual error: echo $exrs->getMessage(); On an aside, I'm currently working with Dave Gardner and Courtney Robinson on a PHP CQL driver. It's still early days as we've not had a huge amount of time to put in to it, but if you want to help out, you're more than welcome.
