"Bad type in structure" means that some property/parameter is of an invalid type. e.g. a string instead of an object, an object of the wrong class, etc.
One thing that jumps out at me is this line... $col->timestamp=time(); I believe that all timestamps must now be defined by an instance of the cassandra_Clock class instead of just a raw timestamp. Try this.. $clock = new cassandra_Clock(); $clock->timestamp = time(); $col->timestamp=$clock; I just got done making a little PHP high level client for Cassandra .7; a big help to me was to open up the various files under the $GLOBALS['THRIFT_ROOT'].'/packages/cassandra/ directory. These files contain all the cassanda_* classes, so you can see explicitly how they work, and what they need to work. Also the cassandra wiki on the API07 is a great tool. http://wiki.apache.org/cassandra/API07 http://wiki.apache.org/cassandra/API Any problems you run into I've probably just ran into myself! :-) Chris.
