php - 毎月第1日曜日を探す方法

Question

phpコードを使用して毎月最初の日曜日の日付が必要です。

私を助けてください。

getSunday();

Answer 1

これは、その月の最初の日曜日を取得するための最良の方法です

echo date("Y-m-d", strtotime("first Sunday of ".date('M')." ".date('Y').""));

Answer 2

日付/時刻拡張子を使用できます。

$start    = new DateTime('2012-12-31');
$end      = new DateTime('2013-12-31');
$interval = DateInterval::createFromDateString('first sunday of next month');
$period   = new DatePeriod($start, $interval, $end, DatePeriod::EXCLUDE_START_DATE);
foreach($period as $time) {
    echo $time->format("F jS") . "<br>\n";
}
/*
January 6th 
February 3rd 
March 3rd 
April 7th 
May 5th 
June 2nd 
July 7th 
August 4th 
September 1st 
October 6th 
November 3rd 
December 1st

Answer 3

DTSの日付を探していたので、次のように見つけました。

$dtsStart = date('Y-m-d 02:00:00', strtotime('Second Sunday Of March 2015'));
$dtsEnd = date('Y-m-d 02:00:00', strtotime('First Sunday Of November 2015'));

Answer 4

function firstSunday($DATE)
    {
        $date = strftime("%Y-%m",$DATE);
        $day = trim(strftime("%e",$DATE));

        for($day; $day <= '7'; $day++){
            $dd = strftime("%A",strtotime($date.'-'.$day));
            if($dd == 'Sunday'){
                return strftime("%Y-%m-%d",strtotime($date.'-'.$day));
            }
        }
    }
