Some PHP functions, like echo , do not need you to use brackets when calling them. Is this true?

Yes, because you can call it like this: echo "hello";

Yes, because echo is a special case.

No, because echo is a language construct and not a function. All PHP functions require you to use brackets when calling them.

No, because all PHP functions require you to use brackets when calling them, except echo, which only requires brackets when you use more than one argument.
