我試圖從我選擇的月份中獲取所有周末日期，但不幸的是沒有得到周末日期，請幫助我如何獲得感謝。
在此處輸入圖片說明
$request->flexibles_months
[ "Dec", "Jan", "Feb"]
控制器
public function listing(Request $request)
{
return $months = explode(',', $request->flexibles_months);
// return $months = [ "Dec", "Jan", "Feb"]
foreach ($months as $i =>$monthValue) {
$weekend = new DatePeriod(
new DateTime($monthValue),
DateInterval::createFromDateString(' 1 hour'),
new DateTime('next Friday 2 days')
);
}
foreach ($weekend as $hours) {
$a = $hours->format("Y-M-d");
}
return $a;
// $a = 2021-Dec-18

這可能對您有所幫助，您可以回傳所有周末日期的陣列作為 UNIX 時間戳。
使用簡單的 HTML 表單
<form>
<input name="start" type="date" />
<input name="stop" type="date" />
<input type="submit" value="Get Weekend" />
</form>
和我的 PHP 代碼
<?php
if(empty($_GET['start']) || empty($_GET['stop']))
die('no data');
$list = Weekendlisting(strtotime($_GET['start']), strtotime($_GET['stop']));
if($list === false)
die('No weekend!');
foreach ($list as $day) {
print(date('c = (l)', $day) . "<br />\n");
}
function Weekendlisting(int $start, int $stop) {
$day_add = 86400;
$return = [];
if($start >= $stop)
return false;
do {
$test = date('N', $start); //ISO-8601 numeric representation of the day of the week (added in PHP 5.1.0)
if($test >= 6)
$return[] = $start;
$start = $start $day_add;
} while ( $stop > $start - $day_add);
return $return;
}
?>
我得到了結果：
2021-12-04T00:00:00 00:00 = (Saturday)
2021-12-05T00:00:00 00:00 = (Sunday)
2021-12-11T00:00:00 00:00 = (Saturday)
2021-12-12T00:00:00 00:00 = (Sunday)
2021-12-18T00:00:00 00:00 = (Saturday)
2021-12-19T00:00:00 00:00 = (Sunday)
2021-12-25T00:00:00 00:00 = (Saturday)
2021-12-26T00:00:00 00:00 = (Sunday)

首先，函式的第一行是 return 陳述句，因此此時函式回傳到呼叫它的位置。無論如何，此行之后的代碼中的任何內容都不會被呼叫。
接下來的事情是，我真的不明白你想要實作什么。我會描述我猜你想做什么。
您將放入幾個月（這里是 12 月、1 月、2 月），結果應該是這些月中的所有周末日期，對嗎？（每周六和周日）

下面的代碼可以稍微清理一下，但它有效。
// Apr and May included for the edge cases.
$months = array('Dec','Jan','Feb','Apr','May');
function weekends($mths){
// so we only have future weekends need to know 'now'.
$now = array('y'=>date('Y'),'m'=>date('m'));
$wkends;
$d;
$m;
$y;
$maxDays;
$saturday;
$sunday;
foreach($mths as $k => $v){
// is the requested month in the past for this year?
$m = date('m',strtotime($now['y'].'-'.$v.'-01'));
// if so, request next year
$y = ($m < $now['m']) ? ($now['y'] 1) : $now['y'];
// What day is the first of the month, 1 for Monday, 7 for Sunday
$d = date('N',strtotime($y.'-'.$m.'-1'));
$saturday = (7 - $d);
$sunday = ($saturday 1);
// And just how many days in the month
$maxDays = date('t',strtotime($y.'-'.$m.'-1'));
do {
// edge case when Sunday is 1st of month
if ($saturday == 0){
$wkends[$v][] = $y.'-'.$m.'-1 (Sun)';
} else {
$wkends[$v][] = $y.'-'.$m.'-'.$saturday.' (Sat)';
if ($sunday <= $maxDays){
$wkends[$v][] = $y.'-'.$m.'-'.$sunday.' (Sun)';
}
}
$saturday = ($saturday 7);
$sunday = ($sunday 7);
} while ($saturday <= $maxDays);
}
}
$result = weekends($months);
var_dump($results);
結果：
