获取指定月份的所有星期，星期日至星期六的星期
Get all weeks of specified month, weeks from Sun-Sat
编辑
我直接在下面尝试了这段代码。已经接近了，但仍然没有找到从每个月的第一个星期日到第一个星期六的星期，然后从星期日到星期六之后的每个星期，直到最后一个星期日到月底。
function get_weeks($month, $year) {
$weeks = array();
$date = DateTime::createFromFormat('mY', $month.$year);
$date->modify('first day of this month');
$end = clone $date;
$end->modify('last day of this month');
$interval = DateInterval::createFromDateString('1 week');
$period = new DatePeriod($date, $interval, $end);
$counter = 1;
foreach ($period as $dt) {
$end_of_week = clone $dt;
$end_of_week->modify('this Saturday');
$weeks[] = sprintf("Week %u: %s - %s",
$counter,
$dt->format('Y-m-d'),
$end_of_week->format('Y-m-d')
);
$counter++;
}
return $weeks;
}
$weeks = get_weeks('08', '2020');
print_r($weeks);
它打印：
Array
(
[0] => Week 1: 2020-08-01 - 2020-08-01
[1] => Week 2: 2020-08-08 - 2020-08-08
[2] => Week 3: 2020-08-15 - 2020-08-15
[3] => Week 4: 2020-08-22 - 2020-08-22
[4] => Week 5: 2020-08-29 - 2020-08-29
)
但它应该打印：
Array
(
[0] => Week 1: 2020-08-01 - 2020-08-01 //correct for this month since 1st day of month and 1st Saturday of this month just happen to be on the same day
[1] => Week 2: 2020-08-02 - 2020-08-08
[2] => Week 3: 2020-08-09 - 2020-08-15
[3] => Week 4: 2020-08-16 - 2020-08-22
[4] => Week 5: 2020-08-23 - 2020-08-29
[5] => Week 6: 2020-08-30 - 2020-08-31 //last Sunday until end of month

我的目标是提取指定月份的指定周数的时间戳数据。我在周日开始我的一周，在周六结束。因此，我试图将特定月份中每周的所有时间戳集中在一起，以便我可以将其绘制出来，显示每周的总小时数。但首先我需要为那个月指定的每个星期的开始和结束。我能够为特定一周的每个工作日执行此操作，但 week/month 设置对我来说太复杂了。
这是我的：
function task_range_month_week($monthweek, $cap_start_raw, $cap_end_raw) {
$start = new DateTime(date('Y-m-d',$cap_start_raw));
$end = new DateTime(date('Y-m-d',$cap_end_raw+86399));
$interval = DateInterval::createFromDateString('1 week');
$period = new DatePeriod($start, $interval, $end);
foreach ($period as $dt) {
//just make it return the values for only a single (specified) week of the month
//if ($dt->format("N") == $monthweek) {
$cap_start = strtotime($dt->format("Y-m-d 00:00:00"));
$cap_end = strtotime($dt->format("Y-m-d 23:59:59"));
//}
}
然后我会像这样调用函数，其中 $cap_start_raw 和 $cap_end_raw 是月份的开始和结束日期，$monthweek 是指定的周数（1-6 ).因此，我正在尝试获取该特定周的周日至周六（或该月的任何部分工作日）的时间。
然后 $cap_start 和 $cap_end 将是指定周范围内的输出。
我想用这个调用那个函数：
//get the 1st week of August 2020, Sun 00:00:00 - Sat 11:59:59 (or whatever days of the month are still in this week)
task_range_month_week(1, 1596240000, 1598918399)
//this would output the 2 new timestamps for that week(1)
//$cap_start = 1XXXXXXXXX;
//$cap_end = 1XXXXXXXXX;
//get the 2nd week of August 2020, Sun 00:00:00 - Sat 11:59:59 (or whatever days of the month are still in this week)
task_range_month_week(2, 1596240000, 1598918399)
//this would output the 2 new timestamps for that week(2)
//$cap_start = 1XXXXXXXXX;
//$cap_end = 1XXXXXXXXX;
etc...
我认为它与 $dt->format() 部分有关，但不确定如何让它工作。
预期输出将 return $cap_start 和 $cap_end 时间戳值。
另一种说法是...
...它 return 是预期输出范围的新开始和结束时间戳。我为每个星期调用 task_range_month_week() 函数，我希望找到单个星期的开始和结束（ $cap_start, $cap_end 输出）。因此，由于 2020 年 8 月的日子跨越 6 个不同的日历周，我将调用该函数 6 次，在本月的情况下，每次调用 $monthweek 指定 1-6。然后在该月的第 1 周的情况下，新的输出范围将在该月 1 日的 00:00:00 处具有 $cap_start，并且由于 $cap_end 恰好下降在星期六，也就是我想结束我的几周（从星期天开始）的时候，它应该在同一天在 23:59:59 输出 $cap_end。然后下一周将从周日到周六，依此类推，直到找到该月所有一周的开始和结束时间，第一周和最后一周的范围只有最大截止时间，即月份开始和结束时间。
如果我将它设置为“1 天”而不是“1 周”，并取消注释 if ($dt->format("N") == $monthweek) 那么当我执行指定周的几天时它会起作用，我已经为该图表设置了这些天。但是如何使其适用于周设置？
有什么想法吗？
我有一个函数可以根据特定月份和年份中的特定周数 (1-6)，将周开始日期和结束日期作为 DateTime 对象数组提供。函数returns出错时为NULL。
function datesWeekInMonth(int $monthWeekNumber, int $month, int $year):?array {
//week from Sun to Sat !
$sat = date_create('first Sat of '.$year.'-'.$month);
if($monthWeekNumber < 1 OR $sat === false) return NULL;
if($monthWeekNumber == 1) return [date_create($year.'-'.$month.'-01'),$sat];
$lastDayOfMonth = date_create('last Day of '.$year.'-'.$month);
for($i=1;$i<$monthWeekNumber;$i++) {
$sun = (clone $sat)->modify('+1 Day');
$sat->modify('next Sat');
}
if($sun > $lastDayOfMonth) return NULL;
return [$sun,min($sat,$lastDayOfMonth)];
}
用法示例：
$result = datesWeekInMonth(3,8,2020); //third week of August 2020
var_dump($result);
/*
array(2) {
[0]=>
object(DateTime)#4 (3) {

}
*/
我决定从算术的角度而不是日期时间的角度来完成这项任务。
也许有一种我没有考虑过的优雅的日期时间对象变异技术，但我不认为我的 function-call-light 方法是可怕的。
我相信我的变量命名将通过我的脚本提供足够的逻辑指导，但实际上我将给定一周的开始和结束日期增加 variable/calulated 数量，并在所有代表了整个月的天数。
