PHP获取包含开始日期和结束日期的年，月和日期的数组

Question

I'm stuck in a PHP function: given a start date (ie. 2011-11-25) and an end date (ie. 2011-03-18), I'd like to get an array containing years > months > dates like this:

Array
(
    [2010] => Array
        (
            [11] => Array
                (
                    [0] => 25
                    [1] => 26
                    [2] => 27
                    [3] => 28
                    [4] => 29
                    [5] => 30
                )

            [12] => Array
                (
                    [0] => 01
                    [1] => 02
                    [2] => 03
                    [3] => 04
                    [4] => 05

                    [17] => 18
                )

        )

)

Googling around I found a function to get an array containing years > months:

function get_months($startstring, $endstring) {
    $time1 = strtotime($startstring);
    $time2 = strtotime($endstring);
    $year1 = date('Y', $time1);
    $year2 = date('Y', $time2);
    $years = range($year1, $year2);

    foreach ($years as $year) {
        $months[$year] = array();
        while ($time1 < $time2) {
            if (date('Y', $time1) == $year){
                $month = date('m', $time1);
                $months[$year][$month] = array();

                $time1 = strtotime(date('Y-m', $time1).' +1 month');
            } else {
                break;
            }
        }
    }
    return $months;
}

// ----------------------------------------------------------------

foreach(array_keys($montharr) as $year){
    foreach($montharr[$year] as $month){
        print "{$year}-{$month}<br>";
    }
}

But I have no idea how implementing days too

Please, any help?

Answer 1

You can use the following function:

<?php
function generateDates($start, $end)
{
  $result = [];

  while ($start <= $end) {
    $result[$start->format('Y')][$start->format('m')][] = $start->format('d');
    $start->add(new DateInterval('P1D'));
  }

  return $result;
}

$start = new DateTime('2010-11-03');
$end = new DateTime('2012-01-15');

print_r(generateDates($start, $end));
