oop - Should I use unset in php __destruct()?

Question

Is it a good practice to unset the variables that you used in a class? Or its an optional?

If its a good practice what is the benefit of using the unset function?

Answer 1

You really don't need to worry about cleaning up your variable declarations in PHP, its garbage collection takes care of all of that for you. Your __destruct() methods are primarily for things like closing persistent connections.
