一分钟内随机睡眠

Question

目前我有以下内容：

$counter = 0;
$actions_per_minute = 6;
$sleep_time = (int)(60 / $actions_per_minute);
do{

    sleep($sleep_time);
    $counter++;

} while($counter < $actions_per_minute);

使用此代码，脚本将每 10 秒 睡眠一次是否可以在 60 秒 内随机设置它不是每 10 秒 所以可能两次在第一个 10 秒 ，睡 7 秒等。 ..

Answer 1

您可以构建一个总计 60 秒的睡眠时间数组，然后在使用时将它们从数组中弹出：

$times = [];
while (array_sum($times) < 60) {
    $min = 1;
    $max = 60 - array_sum($times);
    $times[] = mt_rand($min, $max);
}

可能会将其包装在一个函数中，这样您就可以每分钟获得一个新数组。然后当你使用它时：

sleep(array_pop($times));

Answer 2

生成一个由 N 个随机数 ($actions_per) 组成的列表，这些数字加起来等于某个值 ($total_time)：

$sleep_times = [];
$actions_per = 6;
$total_time = 60;

$sum = 0;
for ($action = 0; $action < $actions_per; $action++ ) {
    $random_interval = rand(0,$total_time);
    array_push($sleep_times, $random_interval);
    $sum = $sum + $random_interval;
}

$scaleFactor = $sum / $total_time;

$checksum = 0;
foreach( $sleep_times as $sleep_time ){
    $scaled = $sleep_time / $scaleFactor;
    $checksum = $checksum + $scaled;
    echo $scaled."\n";
}
echo "Check:".$checksum;

结果：

$actions_per = 6, $total_time = 60:

9.2523364485981
3.9252336448598
12.056074766355

$actions_per = 12, $total_time = 60:
