This article mainly introduces the method of calculating the number of days between dates in PHP programming, involving the conversion and calculation of date and time in PHP. Friends who need it can refer to it.

I didn’t check the PHP manual at the beginning. In this case, I also tried to use a relatively old-fashioned method. The code is implemented like this:

$date_1 = date('Y-m-d'); $date_2= '2012-07-16'; $date1_arr = explode("-",$date_1); $date2_arr = explode("-",$date_2); $day1 = mktime(0,0,0,$date1_arr[1],$date1_arr[2],$date1_arr[0]); $day2 = mktime(0,0,0,$date2_arr[1],$date2_arr[2],$date2_arr[0]); $days = round(($day2 - $day1)/3600/24); echo $days; exit;
Copy after login

Later I googled it. I found that there is a DATE_DIFF method in the PHP manual, which instantiates the datetime class and calls the diff method: PHP version >= 5.3 valid

diff($datetime2); echo $interval->format('%R%a days'); ?>
Copy after login

format('%R%a days'); ?>
Copy after login

The above is the entire content of this article, I hope it will be helpful to everyone's study.
