Get Start and End Days for a Given Week in PHP

Question

I\'m trying to get the week range using Sunday as the start date, and a reference date, say $date, but I just can\'t seem to figure it out.

For example,

Answer 1

To be honest, I have trouble understanding the code you posted ;)

I guess something like this should do the trick:

function get_week($date) {
        $start = strtotime($date) - strftime('%w', $date) * 24 * 60 * 60;
        $end = $start + 6 * 24 * 60 * 60;
        return array('start' => strftime('%Y-%m-%d', $start),
                     'end' => strftime('%Y-%m-%d', $end));
}

Answer 2

I noticed that most of the answers here make use of strtotime/DateTime. While correct, personally I rather calculating dates without using English words.

Here's a simple solution that makes use of mtkime :

$now = time();
$day_of_week = (int)date('w', $now);

$week_start = mktime(0, 0, 0, date('n', $now), date('j', $now)-$day_of_week, date('Y', $now));
$week_end = mktime(23, 59, 59, date('n', $week_start), date('j', $week_start)+6, date('Y', $week_start));

Answer 3

from PHP DateTime doc :

<?php
$date = new DateTime();

$date->setISODate(2008, 2);
$startDay = $date->format('Y-m-d');

$date->setISODate(2008, 2, 7);
$endDay = $date->format('Y-m-d');
?>

Answer 4

You can now use DateTime to get start/end dates of week(s)

function getDateRangeForAllWeeks($start, $end){
    $fweek = getDateRangeForWeek($start);
    $lweek = getDateRangeForWeek($end);
    $week_dates = [];
    while($fweek['sunday']!=$lweek['sunday']){
        $week_dates [] = $fweek;
        $date = new DateTime($fweek['sunday']);
        $date->modify('next day');

        $fweek = getDateRangeForWeek($date->format("Y-m-d"));
    }
    $week_dates [] = $lweek;

    return $week_dates;
}

function getDateRangeForWeek($date){
    $dateTime = new DateTime($date);
    $monday = clone $dateTime->modify(('Sunday' == $dateTime->format('l')) ? 'Monday last week' : 'Monday this week');
    $sunday = clone $dateTime->modify('Sunday this week'); 
    return ['monday'=>$monday->format("Y-m-d"), 'sunday'=>$sunday->format("Y-m-d")];
}

Usage

print_r( getDateRangeForWeek("2016-05-07") );

print_r( getDateRangeForAllWeeks("2015-11-07", "2016-02-15") );
