⚠️ The PHP driver is in maintenance mode. We are still accepting pull-requests and we will occasionally release critical bug fixes, but no ongoing active development is being done currently.

DataStax PHP Driver for Apache Cassandra

A modern, feature-rich and highly tunable PHP client library for Apache Cassandra 2.1+ using exclusively Cassandra's binary protocol and Cassandra Query Language v3. Use the DSE PHP driver for better compatibility and support for DataStax Enterprise.

This is a wrapper around the DataStax C/C++ Driver for Apache Cassandra.

Note: DataStax products do not support big-endian systems.

Getting the Driver

Binary versions of the driver, available for multiple operating systems and multiple versions of PHP, can be obtained from DataStax download server. The source code is made available via GitHub. If you're using DataStax Enterprise use the DSE PHP driver instead.

Note: The driver extension is a wrapper around the DataStax C/C++ Driver for Apache Cassandra and is a requirement for proper installation of the PHP extension binaries. Ensure these dependencies are met before proceeding.

What's new in v1.2.0/v1.3.0

Support for duration
Session::execute() and Session::executeAsync() now support a simple string for the query CQL and a simple array for the query execution option
Full support for Apache Cassandra 2.2 and 3.0+
Support for tinyint and smallint
Support for date and time
Support for user-defined function and aggregate metadata
Support for secondary index and materialized view metadata

Compatibility

This driver works exclusively with the Cassandra Query Language v3 (CQL3) and Cassandra's native protocol. The current version works with:

Apache Cassandra versions 2.1, 2.2 and 3.0+
PHP 5.6, PHP 7.0, and PHP 7.1
- 32-bit (x86) and 64-bit (x64)
- Thread safe (TS) and non-thread safe (NTS)
Compilers: GCC 4.1.2+, Clang 3.4+, and MSVC 2010/2012/2013/2015

If using DataStax Enterprise the DSE PHP driver provides more features and better compatibility.

Quick Start

<?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']);
}

Code examples

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.

Running tests

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 ssh

Once you've logged in to the vagrant VM, run:

cd /usr/local/src/php-driver
./bin/behat
./bin/phpunit
