New Comment:
And use this test case. It don't make use of constructor
Test script:
---------------
abstract class A { abstract static function aa(); } //invalid
//Strict Standards: Static function A::aa() should not be abstract in php shell
code on line 1
interface I { static function ii(); } //valid
abstract class B implements I {} //valid
//class C extends B{} // invalid
//Fatal error: Class C contains 1 abstract method and must therefore be
declared abstract or implement the remaining methods (I::i) in php shell code
on line 1
class D extends B{
static function ii(){echo "I have to be implemented"; }
}

I changed PHP version as it IS revelant
According to this
http://php.net/manual/en/migration52.incompatible.php
Dropped abstract static class functions. Due to an oversight, PHP 5.0.x and
5.1.x allowed abstract static functions in classes. As of PHP 5.2.x, only
interfaces can have them.

Abstract static methods are allowed. Abstract static *constructors* aren't.

Description:
------------
abstract static function in class isn't allowed,
but you can define static function in interface
This leads to funny inconsistency where you can create abstract static function
using interfaces
Test script:
---------------
//abstract class A { abstract static function a(); } //invalid
interface I { static function i(); } //valid
abstract class B implements I {} //valid
//class C extends B{} // invalid
//Fatal error: Class C contains 1 abstract method and must therefore be
declared abstract or implement the remaining methods (I::i) in php shell code
on line 1
class D extends B{
static function i(){echo "I have to be implemented"; }
}
