Question

I\'m trying to find the weekly periods for a given month and year. Dates should start on a Monday and end on a Sunday. If the 1st of the month is a Sunday (Ex May 2011), it

Answer 1

If you need all weeks for selected month, and all dates for selected week, then this is all you need:

function getWeekDays($month, $year)
{
    $p = new DatePeriod(
        DateTime::createFromFormat('!Y-n-d', "$year-$month-01"),
        new DateInterval('P1D'),
        DateTime::createFromFormat('!Y-n-d', "$year-$month-01")->add(new DateInterval('P1M'))
    );

    $datesByWeek = array();
    foreach ($p as $d) {
        $dateByWeek[ $d->format('W') ][] = $d;
    }
    return $dateByWeek;
}

getWeekDays() function returns multi dimension array. first key is week number. 2 level is array, that has dates saved as DateTime object.

Fetch example:

print_r( getWeekDays(5, 2011) ); # May 2011
print_r( getWeekDays(9, 2012) ); # Sep 2012

I had a little time extra, so I written an example ;-)

$datesByWeek = getWeekDays(8, 2012);
$o = '';
$o.= '';
foreach ($datesByWeek as $week => $dates) {
    $firstD = $dates[0];
    $lastD = $dates[count($dates)-1];

    $o.= "";
    $o.= "";
    $N = $firstD->format('N');
    for ($i = 1; $i < $N; $i++) {
        $o.= "";
    }
    foreach ($dates as $d) {
        $o.= "";
            # for selected date do you magic
    }
    $N = $lastD->format('N');
    for ($i = $N; $i < 7; $i++) {
        $o.= "";
    }
    $o.= "";
}
$o.= '
Week
Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
" . $firstD->format('M d') . ' - ' . $lastD->format('M d') . "
-
" . $d->format('d.') . " / 0.00
-
';
echo $o;

Output looks like:
