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，脚本每 10秒就会休眠是否可以在 60秒上随机设置，而不是每隔 10秒< / strong>所以可能两次在第一个 10秒，睡眠7秒等等....

Answer 1

生成一个N个随机数（$ actions_per）的列表，它们加起来一定的值（$ 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：

使用以下方法管理修复它：

//start
$number_of_groups = 6;
$sum_to = 60;
$groups = [];
$group = 0;
$counter = 0;
while(array_sum($groups) != $sum_to) {
    $groups[$group] = mt_rand(1, $sum_to/mt_rand(1,5));
    if(++$group == $number_of_groups) {
        $group  = 0;
    }
}
do{

    $sleep_time = array_pop($groups);
    sleep($sleep_time);
    $counter++;
    echo date("Y-m-d H:i:s")." - we just slept for ".$sleep_time." & we have ".json_encode($groups)." left</br></hr>";

} while($counter < $number_of_groups);
die();
//end
