In this article, you will learn how to subtract a date from another date. You should not confuse this concept with the date_diff() function because the date_diff() function returns the difference between two dates. The date_sub() function subtracts some day, months, years, hours, minutes, or seconds from the date.
What is the syntax of the date_sub() function in PHP?
date_sub(object, interval)
| Parameter | Description |

Examples of the date_sub() function

<?php

date_sub($date,date_interval_create_from_date_string("10 days"));
echo date_format($date,"d-m-y");
?>
