Following the article on the manipulation of dates in SQL, I realized that, in fact, the manipulation of date in php was not so simple and known as that. There are many functions on dates in PHP and I still find a lot of code that gets confused trying to calculate dates with mktime, manipulating timestamps. While a very practical class exists: DateTime. So it is she, and her companions, that I will present.

In the Simple PHP Library (SPL for those close to you), there are classes and interfaces that allow you to simply browse folders and files. It is even possible and very simple to create a filter that allows you to narrow the result.
