Question

我想从星期一开始的那个月开始，并在同一个月的星期日结束。我会提供月份和年份。例如：

$month = '03';
$year = '2014';

那么函数应该返回 2014-03-03 to 2014-03-09作为月份的开始日期，月份的第一个星期一是3月。然后继续到上个月到上周。在2014年3月，31日从星期一开始，但没有在3月完成，它在2014年4月6日结束，所以这不应该计入。

现在，当我将月份作为'04'而不是月份时应该在第一周的31日进行计数。

我希望我清楚自己，对不起语言。到目前为止我已尝试过：

$month = "04";
$year = "2014";
$beg = (int)date('W', strtotime("first day of $year-$month"));
$end = (int)date('W', strtotime("last day of $year-$month"));
$weeks = range($beg, $end);

foreach($weeks as $week) {
    $result = $this->getStartAndEndDate($week, $year);
    print_r($result);
}

function getStartAndEndDate($week, $year)
{
    $time = strtotime("1 January $year", time());
    $day = date('w', $time);
    $time += ((7*$week)+1-$day)*24*3600;
    $return[0] = date('Y-m-d', $time);
    $time += 6*24*3600;
    $return[1] = date('Y-m-d', $time);
    return $return;
}

输出：

Array
(
    [0] => 2014-03-03
    [1] => 2014-03-09
)

    [0] => 2014-03-10

    [1] => 2014-04-06

Answer 1

您可以使用DateTime类：

$dt = new DateTime('1st march');

// is this a monday?
if($dt->format('N') !== '1') {
  // if not, went to next monday
  $dt->modify('next monday');
}

echo $dt->format('Y-m-d')
    . ' to ' . $dt->modify('next sunday')->format('Y-m-d');

输出：

2014-03-03 to 2014-03-09

Answer 2

<?php
function get_weeks($month, $year) {
    $weeks = array();

    $date = DateTime::createFromFormat('mY', $month.$year);
    $date->modify('first Monday of this month');

    $end = clone $date;
    $end->modify('last Monday 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('next Sunday');
        $weeks[] = sprintf("Week %u: %s - %s", 
            $counter,
            $dt->format('Y-m-d'),
            $end_of_week->format('Y-m-d')
        );      
        $counter++;
    }

    return $weeks;
}
$weeks = get_weeks('03', '2014');
print_r($weeks);

Array
(
    [0] => Week 1: 2014-03-03 - 2014-03-09
    [1] => Week 2: 2014-03-10 - 2014-03-16
    [2] => Week 3: 2014-03-17 - 2014-03-23
    [3] => Week 4: 2014-03-24 - 2014-03-30
)
