Do the same principles of differences between singleton and stat class work in different languages?

Question

PHP

Mastering MVC and patterns
https://habrahabr.ru/post/103681/ - a good article about singleton and static class
There is a table, comparisons of singleton and Static class Are the
given comparisons valid for both C# and PHP or is it not so at all?
ps I didn’t find a good article about the stat class in PHP except this one (phpfaq), but it’s about the approach itself and not about the difference

Answer 1

Yes, for all PLs, where there is a singleton and a stat in general.

Answer 2

Actually, singleton should be understood as a crutch. This is a means of preventing the class constructor from reworking.
