Split current month into weeks in php

Question

I want to divide the current month into weeks, like the first day until Saturday, and then Sunday the next Saturday. For example: in the month of May, So I want to break it down like

2016-05-01 to 2016-05-07 2016-05-08 to 2016-05-14 2016-05-15 to 2016-05-21 2016-05-22 to 2016-05-28 2016-05-29 to 2016-05-31 

if I try the code below, I did not get the exact result.

 <?php $start_date = date('Ym-d', strtotime('2016-06-01')); $end_date = date('Ym-d', strtotime('2016-06-30')); $i=1; for($date = $start_date; $date <= $end_date; $date = date('Ym-d', strtotime($date. ' + 7 days'))) { echo getWeekDates($date, $start_date, $end_date, $i); echo "\n"; $i++; } function getWeekDates($date, $start_date, $end_date, $i) { $week = date('W', strtotime($date)); $year = date('Y', strtotime($date)); $from = date("Ymd", strtotime("{$year}-W{$week}+1")); if($from < $start_date) $from = $start_date; $to = date("Ymd", strtotime("{$year}-W{$week}-7")); if($to > $end_date) $to = $end_date; echo $from." - ".$to.'<br>'; } ?> 

i got how

 2016-05-01 - 2016-05-01 2016-05-01 - 2016-05-08 2016-05-08 - 2016-05-15 2016-05-15 - 2016-05-22 2016-05-22 - 2016-05-29 

In a for loop, checking the last set of days, conditon get failed.so it does not calculate 30.31.

How can i do this?

DateTime, DatePeriod and DateInterval are your friends to do it fast!

Watch online .

 <?php /** * @file * Awnser to http://stackoverflow.com/q/37224961/392725 * * @link http://stackoverflow.com/a/37228497/392725 */ date_default_timezone_set('Europe/Paris'); function getWeekDates(DateTimeInterface $date, $format = 'Ym-d') { $dt = \DateTimeImmutable::createFromMutable($date); $first_day = $dt->modify('first day of this month'); $last_day = $dt->modify('last day of this month'); $period = new \DatePeriod( $first_day, \DateInterval::createFromDateString('sunday this week'), $last_day, \DatePeriod::EXCLUDE_START_DATE ); $weeks = [$first_day->format($format)]; foreach ($period as $d) { $weeks[] = $d->modify('-1 day')->format($format); $weeks[] = $d->format($format); } $weeks[] = $last_day->format($format); return array_chunk($weeks, 2); } echo "Weeks of the current month:\n"; $weeks = getWeekDates(new \DateTime('now')); array_walk($weeks, function ($week) { vprintf("%s to %s\n", $week); }); echo "\nWeeks of the month may 2016:\n"; $weeks = getWeekDates(new \DateTime('2016-05')); array_walk($weeks, function ($week) { vprintf("%s to %s\n", $week); }); echo "\nWeeks of the month june 2016:\n"; $weeks = getWeekDates(new \DateTime('2016-06')); array_walk($weeks, function ($week) { vprintf("%s to %s\n", $week); }); echo "\nWeeks of the month october 2016:\n"; $weeks = getWeekDates(new \DateTime('2016-10')); array_walk($weeks, function ($week) { vprintf("%s to %s\n", $week); }); 

Result:

 Weeks of the current month: 2016-05-01 to 2016-05-07 2016-05-08 to 2016-05-14 2016-05-15 to 2016-05-21 2016-05-22 to 2016-05-28 2016-05-29 to 2016-05-31 Weeks of the month may 2016: 2016-05-01 to 2016-05-07 2016-05-08 to 2016-05-14 2016-05-15 to 2016-05-21 2016-05-22 to 2016-05-28 2016-05-29 to 2016-05-31 Weeks of the month june 2016: 2016-06-01 to 2016-06-04 2016-06-05 to 2016-06-11 2016-06-12 to 2016-06-18 2016-06-19 to 2016-06-25 2016-06-26 to 2016-06-30 Weeks of the month october 2016: 2016-10-01 to 2016-10-01 2016-10-02 to 2016-10-08 2016-10-09 to 2016-10-15 2016-10-16 to 2016-10-22 2016-10-23 to 2016-10-29 2016-10-30 to 2016-10-31

Try this, I suppose, you can change the month variable to suit your needs.

 $month=5;//pass here your month $first_date = date("Ym-1"); do{ $last_date = date("Ymd",strtotime($first_date. " +6 days")); $month = date("m",strtotime($last_date)); if($month!=5) $last_date = date("Ymt"); echo "<br>".$first_date." - ".$last_date; $first_date = date("Ymd",strtotime($last_date. " +1 days")); }while($month == 5);

 function getSaturdays($y, $m) { return new DatePeriod( new DateTime("first saturday of $y-$m"), DateInterval::createFromDateString('next saturday'), new DateTime("last day of $y-$m") ); } function list_week_days($year, $month) { $first_month_day = new DateTime("first day of $year-$month") ; echo $first_month_day->format("Ymd\n") . '-'; foreach (getSaturdays($year, $month) as $saturday) { echo $saturday->format(" Ymd\n"); echo '-<br>'; $sunday = $saturday->modify('next Sunday'); echo $sunday->format(" Ymd\n"); } $last_month_day = new DateTime("last day of $year-$month"); echo $last_month_day->format("Ymd\n"); } list_week_days(2016, 5); 

ps I force you to use the DateTime class

The modified Rishi code fixed some problem areas and solved the problem of leap years when he divided February into weeks:

 $weeks = monthToWeeks(2016, '02'); print_r($weeks); function monthToWeeks($y, $m) { $weeks = []; $month = $m; $first_date = date("{$y}-{$m}-01"); do { $last_date = date("Ymd", strtotime($first_date. " +6 days")); $month = date("m", strtotime($last_date)); if ($month != $m) { $last_date = date("Ymt", mktime(0, 0, 0, $m, 1, $y)); if ($first_date > $last_date) { break; } } $weeks[] = [$first_date, $last_date]; $first_date = date("Ymd", strtotime($last_date. " +1 days")); } while($month == intval($m)); return $weeks; }
