Which PHP client library to use with Cassandra?
(Since PHPCassa will no longer be supported and Pandra is abandoned, this question deserves a new answer.)
DataStax PHP Driver for Cassandra is suggested by PHPCassa devs as an alternative that supports CQL, has many excellent features, and is well maintained.
Github and Official website
Update: It now supports PHP 7
Update 2 (2019): It now supports PHP 7.1
I suggest PHPCassa which has
An active support group http://groups.google.com/group/phpcassa
