### Asynchronous IO event dispatcher for PHP

[](#asynchronous-io-event-dispatcher-for-php)

Eventful provides an extensible IO event dispatcher for use in interactive and asynchronous processes.

---

Installation
------------

[](#installation)

This package requires PHP 8.4 or higher.

Install via Composer:

```
composer require decodelabs/eventful
```

### Usage

[](#usage)

Listen for events on IO, Signals and Timers and respond accordingly. If php's Event extension is available, that will be used, otherwise a basic `select()` loop fills in the gaps.

```
use DecodeLabs\Deliverance;
use DecodeLabs\Eventful\Factory;

$broker = Deliverance::newCliBroker();

$eventLoop = Factory::newDispatcher()

    // Run every 2 seconds
    ->bindTimer('timer1', 2, function() use($broker) {
        $broker->writeLine('Timer 1');
    })

    // Listen for reads, but frozen - won't activate until unfrozen
    ->bindStreamReadFrozen($input = $broker->getFirstInputReceiver(), function() use($broker) {
        $broker->writeLine('You said: '.$broker->readLine());
    })

    // Run once after 1 second
    ->bindTimerOnce('timer2', 1, function($binding) use($broker, $input) {
        $broker->writeLine('Timer 2');

        // Unfreeze io reads
        $binding->eventLoop->unfreeze($intput);
    })

    // Check if we want to bail every second
    ->setCycleHandler(function(int $cycles) {
        if($cycles > 10) {
            return false;
        }
    });

/*
Outputs something like:

Timer 2
Timer 1
Timer 1
You said: Hello world
Timer 1
*/
```
