[PHP] 두 날짜 차이 기간 얻기, date_diff()

두 날짜 사이의 기간정보를 얻고 싶을때,

 

 

<?
$start_data = new DateTime('2018-12-01'); 
$end_date = new DateTime('2019-02-20');
$diff_days = date_diff($start_data, $end_date);
 
echo $diff_days->days; // 50
 
print_r($diff_days);
 
?>
 
DateInterval Object ( [y] => 6 [m] => 1 [d] => 12 [h] => 0 [i] => 0 [s] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => 2234 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 )

 

$diff_days 가 객체형태로 반환된다.
