Question

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

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;
}

Answer 1

You will have to write a function:

Algorithm:

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

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