A modern, feature-rich and highly tunable PHP client library for Apache Cassandra (1.2+) and DataStax Enterprise (3.1+) using exclusively Cassandra's binary protocol and Cassandra Query Language v3.
This is a wrapper around the DataStax C/C++ Driver for Apache Cassandra and DataStax Enterprise.

This is the first release candidate of the DataStax PHP Driver. This means that it is mostly feature complete but not entirely stable. Below, you'll find a list of functionality that is already supported as well as what's planned for the upcoming releases.
- Ability to configure connection pooling.
- Ability to configure latency aware load balancing.
- Ability to set native protocol version
- Support for configuring TCP Nodelay and TCP Keepalive.
- Expose Schema Metadata.

<?php
$cluster = Cassandra::cluster() // connects to localhost by default
->build();
$keyspace = 'system';
$session = $cluster->connect($keyspace); // create session, optionally scoped to a keyspace
$statement = new Cassandra\SimpleStatement( // also supports prepared and batch statements
'SELECT keyspace_name, columnfamily_name FROM schema_columnfamilies'
);
$future = $session->executeAsync($statement); // fully asynchronous and easy parallel execution
$result = $future->get(); // wait for the result, with an optional timeout
foreach ($result as $row) { // results and rows implement Iterator, Countable and ArrayAccess
printf("The keyspace %s has a table called %s\n", $row['keyspace_name'], $row['columnfamily_name']);

This driver works exclusively with the Cassandra Query Language v3 (CQL3) and Cassandra's native protocol. The current version works with:
- Apache Cassandra versions 1.2, 2.0 and partially 2.1
- DataStax Enterprise 3.1, 3.2, 4.0 and 4.5
- PHP 5.3.4+
- Compilers: GCC 4.1.2+, Clang 3.4+, and MSVC 2010/2012/2013
NOTE: Apache Cassandra 2.1 support is limited to the Cassandra 2.0 API (native protocol v2), e.g. no user-defined types.

The DataStax PHP Driver uses the amazing Behat Framework
for both end-to-end, or acceptance, testing and documentation. All of the features
supported by the driver have appropriate acceptance tests with easy-to-copy code
examples in the features/ directory.
For your convenience a Vagrantfile with configuration ready for testing is
available. To execute tests, run the following:
git clone https://github.com/datastax/php-driver.git
cd php-driver
git submodule update --init
vagrant up
vagrant sshOnce you've logged in to the vagrant VM, run:
cd /usr/local/src/php-driver
./bin/behat
