int \Workerman\Lib\Timer::add(float $time_interval, callable $callback [,$args = array(), bool $persistent = true])
定时执行某个函数或者类方法html
time_interval
数组
多长时间执行一次,单位秒,支持小数,能够精确到0.001,即精确到毫秒级别。闭包
callback
并发
回调函数注意:若是回调函数是类的方法,则方法必须是public属性
函数
args
ui
回调函数的参数,必须为数组,数组元素为参数值this
persistent
spa
是不是持久的,若是只想定时执行一次,则传递false(只执行一次的任务在执行完毕后会自动销毁,没必要调用Timer::del()
)。默认是true,即一直定时执行。.net
返回一个整数,表明计时器的timerid,能够经过调用Timer::del($timerid)
销毁这个计时器。
