Timer创建定时器设置变量没秒自减，当变量符合条件时处理其他逻辑，怎么实现？(二楼事例)

测试得知：php文件记事本打开另存为ansi格式，发送或接收的中文字符串才能正常显示，否则就是乱码的。
可不可以改成utf8格式也能正常显示中文呢？

timer添加定时器：

$time_init = 300;
$timerId = Timer::add(1, function($time_init){
    echo "time:".$time_init.",status=0\n";
    $time_init -- ;
    if ($time_init <= 295 && $time_init > 290){
        echo "time:".$time_init.",status=1\n";
    }else if ($time_init <= 290){
        echo "time:".$time_init.",status=2\n";
    }
},array($time_init));

怎样才能做到 $time_init 每秒自减呢？现在这样打印出来 $time_init 一直是300，没变~

$time_init = 300;
$timerId = Timer::add(1, function() use (&$time_init){
    echo "time:".$time_init.",status=0\n";
    $time_init -- ;
    if ($time_init <= 295 && $time_init > 290){
        echo "time:".$time_init.",status=1\n";
    }else if ($time_init <= 290){
        echo "time:".$time_init.",status=2\n";
    }
}));

或者

$time_init = 300;
$timerId = Timer::add(1, function(){
    global $time_init;
    echo "time:".$time_init.",status=0\n";
    $time_init -- ;
    if ($time_init <= 295 && $time_init > 290){
        echo "time:".$time_init.",status=1\n";
    }else if ($time_init <= 290){
        echo "time:".$time_init.",status=2\n";
    }
});

或者

$timerId = Timer::add(1, function(){
    static $time_init = 300;
    echo "time:".$time_init.",status=0\n";
    $time_init -- ;
    if ($time_init <= 295 && $time_init > 290){
        echo "time:".$time_init.",status=1\n";
    }else if ($time_init <= 290){
        echo "time:".$time_init.",status=2\n";
    }
});
