# zend-eventmanager [![Build Status](https://secure.travis-ci.org/zendframework/zend-eventmanager.svg?branch=master)](https://secure.travis-ci.org/zendframework/zend-eventmanager) [![Coverage Status](https://coveralls.io/repos/zendframework/zend-eventmanager/badge.svg?branch=master)](https://coveralls.io/r/zendframework/zend-eventmanager?branch=master) zend-eventmanager is designed for the following use cases: - Implementing simple subject/observer patterns. - Implementing Aspect-Oriented designs. - Implementing event-driven architectures. The basic architecture allows you to attach and detach listeners to named events, both on a per-instance basis as well as via shared collections; trigger events; and interrupt execution of listeners. - File issues at https://github.com/zendframework/zend-eventmanager/issues - Documentation is at https://zendframework.github.io/zend-eventmanager/ For migration from version 2 to version 3, please [read the migration documentation](https://zendframework.github.io/zend-eventmanager/migration/intro/). ## Benchmarks We provide scripts for benchmarking zend-eventmanager using the [Athletic](https://github.com/polyfractal/athletic) framework; these can be found in the `benchmarks/` directory. To execute the benchmarks you can run the following command: ```bash $ vendor/bin/athletic -p benchmarks ```
