Swoole 中毫秒定时器(Timer)的使用

间隔定时器， tick 定时器会持续触发，直到调用 clear() 清除为止。

$timer = Swoole\Timer::tick(3000, function (int $timer_id, $param1, $param2) {
    echo "timer_id #$timer_id, after 3000ms.\n";
    echo "param1 is $param1, param2 is $param2.\n";

    Swoole\Timer::tick(14000, function ($timer_id) {
        echo "timer_id #$timer_id, after 14000ms.\n";
    });
}, "A", "B");

一次性定时器，执行完成后会自动销毁。

$str = "Swoole";
$timer = Swoole\Timer::after(1000, function() use ($str) {
    echo "Hello, $str\n";
});

使用定时器 ID 来删除定时器。

var_dump(Swoole\Timer::clear($timer));
