How to achieve time difference in php?

php Find the time difference between two given dates:

1. First convert the two dates into timestamps.

$startdate = strtotime("{$year}-01-01"); 
$enddate = strtotime("{$year}-{$month}-{$day}");

2. Subtract two timestamps.

(End time-Start time)

$diff_seconds = $enddate-$startdate;

This will get the time difference between the two dates, but it will still be counted in seconds, which is not conducive to reading.

Because there are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute; convert 24*60*60=86400, so there are 86400 seconds in a day.

3. Divide the time difference $diff_seconds by 86400, and use floor() to round down to the nearest integer.

$time = floor(($diff_seconds)/86400); 
$time = floor(($diff_seconds)/86400);

4. What is obtained is the number of days, excluding the day of x month and x day, add 1.

This is the total number of days ending on a certain day of a certain month of a certain year.
