Fix the issues reported by phpcs

Above errors/warning has been fixed.

The constants should be preferably declared in an Interface compared to a Class.

In this case, there is no interface where those constants should be placed. Actually, I do not see any gain in defining a class just for a single constant.

phpcs does not always suggest the right changes. It is the developer who needs to understand what is correct and what not.

The MR !5 have solved the issues and there is no class is created and error is solved which is given by phpcs

bindu r → made their first commit to this issue’s fork.
