獲取指定月份的所有周，從周日到周六的周

30秒到達(dá)戰(zhàn)場(chǎng) 2023-09-15 17:06:14

我直接在下面嘗試了這段代碼。它很接近，但仍然找不到從每月 1 號(hào)到第一個(gè)星期六的周，然后是從周日到周六的每周，直到最后一個(gè)周日到月底。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?。篈rray([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)但它應(yīng)該打印：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)

我決定從算術(shù)角度而不是日期時(shí)間角度來(lái)完成這項(xiàng)任務(wù)。

也許有一種我沒(méi)有考慮的優(yōu)雅的日期時(shí)間對(duì)象變異技術(shù)，但我不認(rèn)為我的函數(shù)調(diào)用輕方法是可怕的。

我相信我的變量命名將通過(guò)我的腳本提供足夠的邏輯指導(dǎo)，但實(shí)際上，我通過(guò)變量/計(jì)算量增加給定周的開(kāi)始和結(jié)束天數(shù)，并在整個(gè)月的所有天數(shù)都達(dá)到時(shí)終止循環(huán)。代表。

代碼：（演示）

function get_weeks($month, $year) {

$weeks = [];

$ym = $year . '-' . $month;

$final = date('t', strtotime($ym));

$firstSat = date('d', strtotime("first Saturday of $ym"));

$d = 1;

$weekNo = 0;

do {

$weekEnd = $d === 1 ? $firstSat : min($final, $d + 6);

$weeks[] = sprintf(

"Week %d: %s-%02d - %s-%02d",

++$weekNo,

$ym,

$d,

$ym,

$weekEnd

);

$d = $weekEnd + 1;

} while ($weekEnd < $final);

return $weeks;

}

foreach (['01','02','03','04','05','06', '07', '08', '09', '10', '11', '12'] as $month) {

echo var_export(get_weeks($month, '2020'), true) . "\n";

}

我有一個(gè)函數(shù)，它根據(jù)特定月份和年份中的特定周數(shù) (1-6) 以 DateTime 對(duì)象數(shù)組的形式提供周開(kāi)始日期和結(jié)束日期。如果發(fā)生錯(cuò)誤，該函數(shù)將返回 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)];

}

使用示例：

$result = datesWeekInMonth(3,8,2020); //third week of August 2020

var_dump($result);

/*

array(2) {

[0]=>

object(DateTime)#4 (3) {

["date"]=>

string(26) "2020-08-09 00:00:00.000000"

["timezone_type"]=>

int(3)

["timezone"]=>

string(13) "Europe/Berlin"

}

[1]=>

object(DateTime)#1 (3) {

["date"]=>

string(26) "2020-08-15 00:00:00.000000"

["timezone_type"]=>

int(3)

["timezone"]=>

string(13) "Europe/Berlin"

}
