I stand by my request because of cohesion.
I often see useless code in derived classes, e.g.:
function __construct($name) {
parent::__construct($name);
}
which does absolutely nothing and I delete this code, because php will do it
automatically.
For the same reason I'd like to remove
function __construct() {
;
}
which also does absolutely nothing and php will do the same automatically
EXCEPT
in the case I described.
So, I stand by my request :)

yes, you can instantiate a calss without a constructor be declared, but that
doesn't mean there is default empty constructor.
in PHP, constructor most like a magic method which will be called after a
object instantiated immediatlely.
so if there is no constructor for a class, the new operator still can
instantiate a class. but you can't call a no-exists constructor directly :)

Well you can call:
$base = new Base();
which works, because php uses default, empty constructor.
If new operator can call it, why derived classes can't?

Actually, there is no `default constructor` in PHP, you should decalare one be
fore you call to it.
I think this should be mark as a feature request.
