Currently, the latest version is 2.0.2. This SDK should be used for all development against Couchbase Server versions from 2.5 to 3.x.

Linux users will be able to install the PHP SDK with pecl as follows:

$ pecl install couchbase

Additionally, the SDK team publishes Windows binaries, which may be found at http://docs.couchbase.com/developer/php-2.0/download-links.html. The source code for the library is available on GitHub at https://github.com/couchbase/php-ext-couchbase.

Here are a few snippets that demonstrate the basics of using the Couchbase PHP SDK:

//Configure the cluster
$cluster = new CouchbaseCluster('http://127.0.0.1:8091');

//Open a bucket connection
$bucket = $cluster->openBucket('default');

// Close the bucket connection
cluster.disconnect();
