<?php
$start_date = date('Y-m-d', strtotime('2016-06-01'));
$end_date = date('Y-m-d', strtotime('2016-06-30'));
$i=1;
for($date = $start_date; $date <= $end_date; $date = date('Y-m-d', strtotime($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));
$from = date("Y-m-d", strtotime("{$year}-W{$week}+1"));
if($from < $start_date) $from = $start_date;
$to = date("Y-m-d", strtotime("{$year}-W{$week}-7"));
if($to > $end_date) $to = $end_date;
echo $from." - ".$to.'<br>';
}
?>
i got like
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 for loop, while checking last set of days, conditon get failed .so it doesnt calculate 30,31.
How can i do that?

Answer 1

DateTime, DatePeriod and DateInterval are your friends to do that quickly!
See online.

date_default_timezone_set('Europe/Paris');
function getWeekDates(DateTimeInterface $date, $format = 'Y-m-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);
});

Try like this, I assume you can change month variable according to your need.
$month=5;//pass here your month
$first_date = date("Y-m-1");
do{
$last_date = date("Y-m-d",strtotime($first_date. " +6 days"));
$month = date("m",strtotime($last_date));
if($month!=5)
$last_date = date("Y-m-t");
echo "<br>".$first_date." - ".$last_date;
$first_date = date("Y-m-d",strtotime($last_date. " +1 days"));
}while($month == 5);

Modified Rishi's code, fixed some problem places and solved the problem of leap years when splitting February into weeks:
$weeks = monthToWeeks(2016, '02');
print_r($weeks);
function monthToWeeks($y, $m)
{
$weeks = [];
$month = $m;
$first_date = date("{$y}-{$m}-01");
do {
$last_date = date("Y-m-d", strtotime($first_date. " +6 days"));
$month = date("m", strtotime($last_date));
if ($month != $m) {
$last_date = date("Y-m-t", mktime(0, 0, 0, $m, 1, $y));
if ($first_date > $last_date) {
break;
}
}
$weeks[] = [$first_date, $last_date];
$first_date = date("Y-m-d", strtotime($last_date. " +1 days"));
} while($month == intval($m));
return $weeks;
}

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 $first_month_day->format("Y-m-d\n") . '-';
foreach (getSaturdays($year, $month) as $saturday) {
echo $saturday->format(" Y-m-d\n");
echo '-<br>';
$sunday = $saturday->modify('next Sunday');
echo $sunday->format(" Y-m-d\n");
}
$last_month_day = new DateTime("last day of $year-$month");
echo $last_month_day->format("Y-m-d\n");
}
list_week_days(2016, 5);
p.s.
I encorege you to use DateTime class
