PHP : how to compute the difference between two dates

Question

I want to find the number of days between two dates. Which PHP function should I use to calculate the difference between two dates?

Answer 1

PHP function date_diff() can be used to calculate the difference between two dates.

Here is an example:

<?php
$date1=date_create("2020-6-15");
$date2=date_create("2021-1-12");
$diff=date_diff($date1,$date2);
echo $diff->format("%R%a days");
?>

The above code will return +211 days.
