Installing the DataStax PHP driver

Installing the DataStax PHP driver

Scylla uses the same drivers as Cassandra. To install the DataStax PHP driver, you first need to install the C++ driver:

git clone https://github.com/datastax/cpp-driver.git
cd cpp-driver
git checkout 2.2.2
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
make
sudo make install

You can then install the PHP extension:

sudo pecl install cassandra

Remember to register the extension in php.ini:

sudo sh -c "echo 'extension=cassandra.so' >> /etc/php.ini"

To test the PHP driver, create a PHP source file scylla.php that looks as follows:

<?php

$cluster   = Cassandra::cluster()->build();

$keyspace  = 'system';
$session   = $cluster->connect($keyspace);
$statement = new Cassandra\SimpleStatement('SELECT keyspace_name, columnfamily_name FROM schema_columnfamilies');
$future    = $session->executeAsync($statement);
$result    = $future->get();

foreach ($result as $row) {
    printf("The keyspace %s has a table called %s\n", $row['keyspace_name'], $row['columnfamily_name']);
}

?>

Start up a Scylla node and run the example program:

$ php scylla.php
