<?php 

set_time_limit();

function sel($time,$number,$count){
    if($count > ){
        sel($time,$number,$count);
        return ;
    }else{
        if(time() > intval($time)){
            $count++;
            @sel($time+$number,$number,$count);
        }else{
            task();
            $time = $time + $number * $count;
            $count++;
            sleep($number);
            @sel($time,$number,$count);
        }
    }
}

echo time();
sel(+*,,);
//echo '<br>'.time();

function task(){
    echo '<br> This is task'.time().'<br>';
}

?>

sel(1473662611+8*3600,1,2); 中的1473662611  要是time() 转化出来，再填写上去，否则失效
