How to set timer in swoole

Set timer

swoole provides JavaScript-like setInterval/setTimeout asynchronous high-precision timer with millisecond-level granularity.

It is also very simple to use. (Recommended learning: swoole video tutorial)

Program code

//每隔2000ms触发一次
swoole_timer_tick(2000, function ($timer_id) {
    echo "tick-2000ms\n";
});
//3000ms后执行此函数
swoole_timer_after(3000, function () {
    echo "after 3000ms.\n";
});

The swoole_timer_tick function is equivalent to setInterval and is continuously triggered

The swoole_timer_after function is equivalent to setTimeout, which is only triggered once at the agreed time.

The swoole_timer_tick and swoole_timer_after functions will return an integer, indicating the ID of the timer.

You can use swoole_timer_clear to clear this timing. The parameter is the timer ID
