Couchbase has released the Beta version of PHP SDK 2.1, which now supports PHP version 7. A final version is anticipated before the General Availability (GA) release, which will include new features from the upcoming server update. Users can install the beta version via PECL or download it from the Couchbase SDK Downloads site, but they must ensure libcouchbase 2.5 or higher is installed first. Any issues can be reported on the Couchbase Communities site or through their issues tracker, and users are encouraged to stay updated on future developments.
