Timer創(chuàng)建定時器設(shè)置變量沒秒自減，當變量符合條件時處理其他邏輯，怎么實現(xiàn)？(二樓事例)

測試得知：php文件記事本打開另存為ansi格式，發(fā)送或接收的中文字符串才能正常顯示，否則就是亂碼的。
可不可以改成utf8格式也能正常顯示中文呢？

timer添加定時器：

$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));

怎樣才能做到 $time_init 每秒自減呢？現(xiàn)在這樣打印出來 $time_init 一直是300，沒變~

暫無評論

打賞

$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";
    }
});
