如何获取给定月份的每周的日期间隔？ [英] How to get the date interval for each week in a given month?

问题描述

有一种方法可以在一个月的PHP中获取每周的开始/结束日期吗？
所以例如，如果我采取这个月（2011年11月），我需要返回

Is there a way to get the date start/end for each week in PHP given a month? So for example if i take this month(Nov 2011) i need to return

30 Oct ->  5 Nov
 6 Nov -> 12 Nov
13 Nov -> 19 Nov
20 Nov -> 26 Nov
27 Nov ->  3 Dec

LE：

我做了，以防其他人需要它。代码不漂亮，但它的工作原理我需要它。

Here's what i made in case some one else needs it. The code is not pretty but it works as i need it.

public function getMonthWeeks($month, $year)
{
    $month = intval($month);

    if ($month < 1) {
        $month = 1;
    }

    if ($month > 12) {
        $month = 12;
    }

    $tsfdOfMonth = mktime(0, 0, 0, $month, 1, $year);
    $dayOfWeek   = idate('w', $tsfdOfMonth);

    $tIntervalStart = $tsfdOfMonth;
    $tNextMonth     = idate('m', strtotime("+1 month", $tsfdOfMonth));

    if ($dayOfWeek > 0) {
        $tStr = sprintf("-%d %s",
            $dayOfWeek,
            $dayOfWeek == 1 ? 'day' : 'days'
        );
        $tIntervalStart = strtotime($tStr, $tsfdOfMonth);
    }

    $resultDates = array();

    $tsStart = $tIntervalStart;
    $tsEnd   = strtotime('+6 days', $tsStart);

    while (true) {
        $rObj = new stdClass;
        $rObj->LinkStr = sprintf("%s %s - %s %s",
            date('M', $tsStart), date('d', $tsStart),
            date('M', $tsEnd),   date('d', $tsEnd)
        );
        $rObj->DateStart = date('Y-m-d', $tsStart);
        $rObj->DateEnd   = date('Y-m-d', $tsEnd);

        $resultDates[] = $rObj;

        if (idate('m', strtotime('+1 day',  $tsEnd)) == $tNextMonth) {
            break;
        }

        $tsStart = strtotime('+1 day',  $tsEnd);
        $tsEnd   = strtotime('+6 days', $tsStart);
    }

    return $resultDates;
}

推荐答案

你将不得不写一个功能：

You will have to write a function:

算法：

1. 获取月份的星期几。


2. 减去必要的天数到达星期天 - 您现在有月份的第一个星期天的日期（可能是上个月的上个月）。


3. 添加六天以确定该周的星期六。


4. 添加一天以确定下周的星期天。


5. 重复3和4，直到我们不再在当前月份

1. Get day of week of first of month.
2. Subtract necessary number of days to reach a Sunday--you now have date of the first "sunday" of the month (possibly last sunday of previous month).
3. Add six days to determine the Saturday of that week.
4. Add one day to determine the Sunday of the next week.
5. repeat 3 and 4 until we are no longer in the current month

两个功能将非常有帮助： $ saturdaytimestamp = strtotime（+ 6天，$ sundaytimestamp）和 $ dayofweek = idate（'w'，$ timestamp）;

Two features will be very helpful: $saturdaytimestamp = strtotime("+6 days", $sundaytimestamp) and $dayofweek = idate('w', $timestamp);
