To count the total number of days between two dates, use the DateTime class and compare them via diff() method with the following few lines of code
$date1 = new DateTime('2020-01-01');
$date2 = new DateTime('2020-02-15');
print_r($date1->diff($date2));And the output will be:
DateInterval Object ( [y] => 0 [m] => 1 [d] => 14 [h] => 0 [i] => 0 [s] => 0 [f] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => 45 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 )
