PHP Kafka Client

This is a Kafka client library for PHP ^7.4 and ^8.0 with a slim librdkafka binding via FFI.

It supports the same interfaces as the PHP RdKafka extension ^5.0 and ^6.0.

Supported Features

• Consumer (low and high level)
• Producer (with support for transactional producing)
• Admin Client
• Mock Cluster to simplify integration tests (even with error situations)
• Support for error handling and logging via callbacks

Runtime Requirements

• PHP ^7.4 or ^8.0 with extensions FFI enabled
• librdkafka ^1.0.0 or ^2.0.0
• Conflicts: RdKafka extension
• Suggested:
  • zend opcache extension for preloading
  • pcntl extension for faster shutdown in request/response context

Note: From PHP 8.3 onwards, you must disable the stack overflow check by setting zend.max_allowed_stack_size=-1 in your php.ini. This is necessary because FFI callbacks are executed off the main thread, and the overflow checks do not handle this scenario properly.

Note: Support for macOS and Windows is experimental.

Installation

composer require idealo/php-rdkafka-ffi

Note: Expect breaking changes along all 0.* pre-releases. This changes may depend on upcoming major releases of the RdKafka extension or improved interfaces for the experimental features like transactional producer, mock cluster and admin client.
