PHP class instantiation. To use or not to use the parenthesis?

I'm learning PHP from an O'reilly book "Learning PHP, MySQL and Javascript". I'm half way through learning a开发者_开发知识库bout objects etc.

I've noticed that sometimes the writer calls objects in two different ways.

• $example = new Object
• $example = new Object()

They both seem to work fine for me. Is there a preferred way or best practice? Is there a reason for this?

Personally I prefer to include the parenthesis. helps to remind you the constructor is a method that you can override.

But this could just be because I learned OOP in C++.

Whatever you do, just be consistent.
