A new beta release of the PHP SDK has been announced, featuring minor bug fixes and initial support for cross-SDK data types. The full API documentation is accessible online, and installation instructions vary based on the operating system. For Linux, users can build and install the library from the source code, while Windows users have the option to download pre-built binaries specific to various PHP versions and architectures. It is essential to have libcouchbase 2.4.0 installed before adding the PHP extension. Users are encouraged to report issues through the Couchbase Communities site or the issues tracker, fostering community support and feedback.
