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.
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();
