Split date ranges into corresponding weeks - php

Question

I have date ranges called from and to.I want to convert it to weeks.
Suppose from date is 1-10-2014 and to date is 31-10-2014
Then result is:
1st week : 01-10-2014 to 04-10-2014
2nd : 05-102014 to 11-10-2014
3rd : 12-10-2014 to 18-10-2014
4th : 19-10-2014 to 25-10-2014
5th : 26-10-2014 to 31-10-2014
In php.I try several code but that didn't given the absolute result only give 01 to 7 , 8 to 14 etc.
Pls help.
I already try answers from

Answer 1

This snippet uses Sunday as the first day of the week:
$start = new DateTime('2014-10-01');
$end = new DateTime('2014-10-31 23:59');
$interval = new DateInterval('P1D');
$dateRange = new DatePeriod($start, $interval, $end);
$weekNumber = 1;
$weeks = array();
foreach ($dateRange as $date) {
$weeks[$weekNumber][] = $date->format('Y-m-d');
if ($date->format('w') == 6) {
$weekNumber++;
}
}
Each week will have all the days in it.
If you just want the first and last days of each week then you can just use array_shift and array_pop to get them. For example, for the first week you can use:
$wk1Start = array_shift($weeks[1]); //gives you first day of week 1
$wk1End = array_pop($weeks[1]); // give you the last day of week 1
If you want the start and end dates for each week, here is a way of doing it:
$ranges = array_map(function($week) {
return 'start: ' . array_shift($week)
. ', end: ' . array_pop($week); },
$weeks);
This is the output of $ranges for me:
Array
(
[1] => start: 2014-10-01, end: 2014-10-04
[2] => start: 2014-10-05, end: 2014-10-11
[3] => start: 2014-10-12, end: 2014-10-18
[4] => start: 2014-10-19, end: 2014-10-25
[5] => start: 2014-10-26, end: 2014-10-31
)

You can easily change the week starting day (set to Monday at the moment):
$fromDate = '2018-05-03';
$toDate = '2018-08-11';
$result = getWeekRanges($fromDate, $toDate);
array_walk_recursive($result, 'applyFormat');
echo '<pre>';
print_r($result);
echo '</pre>';
function getWeekRanges($start, $end) {
$timeStart = strtotime($start);
$timeEnd = strtotime($end);
$out = [];
$milestones[] = $timeStart;
$timeEndWeek = strtotime('next Monday', $timeStart);
while ($timeEndWeek < $timeEnd) {
$milestones[] = $timeEndWeek;
$timeEndWeek = strtotime('+1 week', $timeEndWeek);
}
$milestones[] = $timeEnd;
$count = count($milestones);
for ($i = 1; $i < $count; $i++) {
if( $i == $count - 1) {
$out[] = [
'start' => $milestones[$i - 1],
'end' => $milestones[$i]
];
}else{
$out[] = [
'start' => $milestones[$i - 1],
'end' => $milestones[$i] - 1
];
}
}
return $out;
}
function applyFormat(&$item) {
$item = date('Y-m-d', $item);
}

Try
$start_date = date('Y-m-d', strtotime('2014-10-01'));
$end_date = date('Y-m-d', strtotime('2014-10-31'));
$i=1;
for($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{$week}+1")); //Returns the date of monday in week
if($from < $start_date) $from = $start_date;
$to = date("Y-m-d", strtotime("{$year}-W{$week}-7")); //Returns the date of sunday in week
if($to > $end_date) $to = $end_date;
echo "$i th ".$from." to ".$to.'<br>';
}
output :-
1 th 2014-10-01 to 2014-10-05
2 th 2014-10-06 to 2014-10-12
3 th 2014-10-13 to 2014-10-19
4 th 2014-10-20 to 2014-10-26
5 th 2014-10-27 to 2014-10-31
