How do you handle reliable event dispatching in PHP? (Introducing PHPOutbox)

Handling events in distributed systems often leads to the "dual write" problem—where saving state to the database succeeds, but publishing the corresponding event fails.

To solve this, I built PHPOutbox, a package that implements the Transactional Outbox pattern to guarantee at-least-once event delivery for PHP applications.

As I prepare for launch, I’d love to hear from the community:

• What tools or patterns are you currently using to ensure reliable event dispatching?

• What specific edge cases or pain points would you want a PHP transactional outbox package to handle?

Any early thoughts, questions, or feedback are highly appreciated!
