Breaking changes from 6.x

Starting from elasticsearch-php 7.4.0, we generate a PHP E_USER_DEPRECATED notice every time you use a deprecated parameters for Elasticsearch. We decided to add this notice to facilitate the code refactoring with the new API specification of Elasticsearch (for example the usage of typeless APIs, see below).

From 7.4.1, we mitigated the usage of E_USER_DEPRICATED warning by using the @ operator. The operator suppresses the error message, however, it is still possible to catch it by using a custom error handler:

set_error_handler(function ($errno, $errstr) {
    var_dump($errstr);
}, E_USER_DEPRECATED);

@trigger_error('Deprecation message here', E_USER_DEPRECATED);

Elasticsearch 7.0 deprecated APIs that accept types, introduced new typeless APIs, and removed support for the default mapping. Read this blog post for more information.

Added type hints and return type declarations in all the code base where possible. See PR #897.

We require using PHP 7.1+ for elasticsearch-php. PHP 7.0 is not supported since 1st Jan 2019. Refer PHP supported version for more information.
