Programming Elasticsearch with PHP

In this article, we introduce the usage of Elasticsearch in PHP. Elasticsearch lets you add advanced searching features that you can't easily do with a traditional database. We present the official PHP client showing some basic features like indexing, bulk (indexing multiple documents), and search. We also show some more advanced client usage, like logging, transfer statistics, and async requests. Last but not least, we present some latest features of Elasticsearch, such as aggregations and the schema-on-read available from version 7.12.
