I tend to only use parenthesis when I've overwritten the constructor to allow parameters to be passed into the instantiantion request.

See example classes below.  Maybe this is just me, if you haven't written a __construct method it shouldn't matter which you use.  I'm sure there's no overhead using parenthesis when you haven't overwritten the __construct.
<?php
 

	class Dog {

		

		public function __construct ($dog_color) {

			//	Whatever else here.

		}

		

	}

	

	class Cat {

		

	}

	

	$dog = new Dog ('brown');

	$cat = new Cat;

	

?>
