How to increase the date in php?

PHP adds one day to the current date and one day to the specified date

1. Add one day to the current time? One hour?

<?php
echo "今天:",date(&#39;Y-m-d H:i:s&#39;),"<br>";
echo "明天:",date(&#39;Y-m-d H:i:s&#39;,strtotime(&#39;+1 day&#39;));
?>

The previous line outputs the current time, and the next line outputs tomorrow's time

Similarly add one year, one hour, one minute, one month...

echo "明天:",date('Y-m-d H:i:s',strtotime('+1 day'));
echo "明天:",date('Y-m-d H:i:s',strtotime('+1 hour'));
echo "明天:",date('Y-m-d H:i:s',strtotime('+1 minute'));
echo "明天:",date('Y-m-d H:i:s',strtotime('+1 mouth'));

Here 1 day can modify parameter 1 to any number you want. Day can also be changed to year (year), month (month) ), hour (hour) minute (minute), second (second) such as:

date('Y-m-d H:i:s',strtotime("+1 day +1 hour +1 minute");
