I’ve always assumed that – in the absence of constructor parameters – the parentheses (curly brackets) follow the class name when creating a class instance, were optional, and that you could include or exclude them at your own personal whim.
That these two statements were equal:
$foo = new bar;
$foo = new bar();
Am I right? Or is there some significance to the brackets that I am unaware of?
I know this sounds like a RTM question, but I’ve been searching for a while (including the entire PHP OOP section) and I can’t seem to find a straight answer.
They are equivalent. If you are not coding by any code convention, use which you like better. Personally, I like to leave it out, as it is really just clutter to me.
