The new PHP client for Elasticsearch 8, developed by Enrico Zimuel, represents a significant update from its predecessor, with a complete architectural redesign that improves developer experience and performance. Adopting PSR standards, the client shifts to a pluggable system using HTTPlug and offers backward compatibility with version 7, maintaining the same APIs while introducing a new response format compliant with the PSR-7 interface. Key features include autocompletion capabilities through the Psalm project, a pluggable architecture that uses the elastic-transport-php library for flexible connectivity options, and enhanced security with default TLS support. The client also supports asynchronous operations by utilizing HTTPlug's Promise interface, reducing both codebase size and memory usage significantly compared to the previous version. These updates aim to optimize interaction with Elasticsearch, offering a more efficient, secure, and versatile experience for developers.
