I understand the discussion above. The warning is because some possible method calls may fail due to
incomplete knowledge at compile-time.
However this causes the warning:
class A { public function foo(StdClass $a) {;}}
class B extends A { public function foo($a) {;}}
as does this:
class A { public function foo($a) {;}}
class B extends A { public function foo(StdClass $a) {;}}
In the case of
function bar(A $a, A $b){$a->foo($b);}
The second form can fail at run-time, but the first can not and should not trigger the error.

was wondering why the order of the class declarations affects whether a notice
is given, that is while
abstract class B extends A {
public static function foo($str){ echo $str; }
}
abstract class A {
public static function foo(){ echo 'bar'; }
}
causes the strict standard notice to show, the reversed order does not:
abstract class A {
public static function foo(){ echo 'bar'; }
}
abstract class B extends A {
public static function foo($str){ echo $str; }
}

This is not a bug in PHP, this is a flaw in your understanding of PHP and how it
handles method overloading. If your child class inherits from the parent class
and you override one of the parent class's methods, you must still pass it the
same number of parameters. Ex:
abstract class B extends A {
public static function foo($str){ echo $str; }
}
abstract class A {
public static function foo(){ echo 'bar'; }
}
What you will notice is that class A has a method "foo" which takes no
parameters. We then extend A with class B which overrides the method "foo" and
gives it a parameter "$str". This method overload is causing the strict error.
If you want a fix, make the parameter optional and it should remove the strict
warning. This fix has been tested with the __autoload function for class
loading.

I have exactly the same problem.
Autoload() is called for the subclass before the class. A error E_STRICT is
throw.
I use PHP 5.3.2-1 on Ubuntu Serveur 10.04
It append for me when I use the design pattern sigleton and when I call the
function getInstance() of the subclass. This function have to return an instance
of the subclass but the error E_STRICT is throw.
I check the change log of PHP 5.3.3-1 but I seen nothing about this.
