laminas-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/laminas/laminas-eventmanager/issues
• Documentation is at https://docs.laminas.dev/laminas-eventmanager/

For migration from version 2 to version 3, please read the migration documentation.

We provide scripts for benchmarking laminas-eventmanager using the PHPBench framework; these can be found in the benchmarks/ directory.

To execute the benchmarks you can run the following command:

$ vendor/bin/phpbench run --report=aggregate
