Answer 1

If you have a month wise get the last date of the month then,

public function getLastDateOfMonth($month)
    {
        $date = date('Y').'-'.$month.'-01';  //make date of month 
        return date('t', strtotime($date)); 
    }

$this->getLastDateOfMonth(01); //31

Answer 2

Carbon API extension for PHP DateTime

Carbon::parse("2009-11-23")->lastOfMonth()->day;

or

Carbon::createFromDate(2009, 11, 23)->lastOfMonth()->day;

will return

30

Answer 3

This a much more elegant way to get the end of the month:

  $thedate = Date('m/d/Y'); 
  $lastDayOfMOnth = date('d', mktime(0,0,0, date('m', strtotime($thedate))+1, 0, date('Y', strtotime($thedate)))); 

Answer 4

This should work:

$week_start = strtotime('last Sunday', time());
$week_end = strtotime('next Sunday', time());

$month_start = strtotime('first day of this month', time());
$month_end = strtotime('last day of this month', time());

$year_start = strtotime('first day of January', time());
$year_end = strtotime('last day of December', time());

echo date('D, M jS Y', $week_start).'<br/>';
echo date('D, M jS Y', $week_end).'<br/>';

echo date('D, M jS Y', $month_start).'<br/>';
echo date('D, M jS Y', $month_end).'<br/>';

echo date('D, M jS Y', $year_start).'<br/>';
echo date('D, M jS Y', $year_end).'<br/>';

I needed the last day of the next month, maybe someone will need it:

echo date("Y-m-t", strtotime("next month")); //is 2020-08-13, return 2020-09-30

Answer 6

If you use the Carbon API extension for PHP DateTime, you can get the last day of the month with:

$date = Carbon::now();
$date->addMonth();
$date->day = 0;
echo $date->toDateString(); // use toDateTimeString() to get date and time
