Promise-based non-blocking operations.
======================================

[](#promise-based-non-blocking-operations)

To be able to run asynchronous code in PHP, a loop needs to run in the background to observe and dispatch events, and handle the resolution of promises.

This repository provides the concepts of a `Loop`, different `Timer` implementations and a publish-subscribe model for `Event` objects.

-------------

[](#example-usage)

A loop with three individual timers at 1 second, 5 seconds and 10 seconds.

```
$timeAtScriptStart = microtime(true);

$timer = new IndividualTimer();
$timer->addTriggerTime($timeAtScriptStart + 1);
$timer->addTriggerTime($timeAtScriptStart + 5);
$timer->addTriggerTime($timeAtScriptStart + 10);

$timer->addCallback(function() use($timeAtScriptStart) {
	$now = microtime(true);
	$secondsPassed = round($now - $timeAtScriptStart);
	echo "Number of seconds passed: $secondsPassed", PHP_EOL;
});

$loop = new Loop();
$loop->addTimer($timer);
echo "Starting...", PHP_EOL;
$loop->run();
```
