Subject Re: php cql driver issues
Date Fri, 27 May 2011 09:14:17 GMT
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.
The base repo (for now) is http://github.com/nicktelford/php-cql
