@szopen 貌似沒有復雜啊

//enable ticks

declare (ticks = 1);

//setTimeout event list

$timeoutQueue = new SplObjectStorage;

register_tick_function(function() {

global $timeoutQueue;

foreach ($timeoutQueue as $v) {

$callBack = $v();

if (is_callable($callBack)) {

$callBack();

$timeoutQueue->detach($v);

}

}

});

register_shutdown_function(function() {

global $timeoutQueue;

while($timeoutQueue->count()) {

foreach ($timeoutQueue as $v) {

$callBack = $v();

if (is_callable($callBack)) {

$callBack();

$timeoutQueue->detach($v);

}

}

usleep(1000);

}

});

function setTimeOut($callback, $time)

{

global $timeoutQueue;

$end = microtime(true) * 1000 + $time;

$f = function() use ($callback,$end) {

if (microtime(true)*1000 >= $end) {

return $callback;

} else {

return false;

}

};

$timeoutQueue->attach($f);

return $f;

}

function clearTimeout(Closure $f) {

global $timeoutQueue;

$timeoutQueue->detach($f);

}

setTimeOut(function() {

echo 'aaaa';

},3000);

setTimeOut(function() {

echo 'bbbb';

},6000);
