Description:
------------
When a static method is called through reflection, late static binding does not work. Probably because the getMethod() returns the method associated to the parent class.

Test script:
---------------
class A{
  public static function call(){
    static::callLate();
  }

  public static abstract function callLate();
}

class B{
  public static function callLate(){
    echo 'Late static binding';
  }
}

B::call();
$class = new ReflectionClass('B');
$class->getMethod('call')->invoke(null);

Expected result:
----------------
Late static binding
Late static binding

Actual result:
--------------
Late static binding
Cannot call abstract method B::callLate()

I experienced this bug when building a new automation framework using PHPUnit + 
selenium.

IT seems that PHPUnit uses reflection to instantiate a static function called 
suite which handles an array of browsers and duplicating a testcase to run in 
each one.

I was on the latest ubuntu package: PHP 5.3.3-1ubuntu9.5 with Suhosin-Patch 
(cli) (built: May  3 2011 00:49:55)

I got around it by switching the reflection to call_user_func but this should 
probably be fixed as PHPUnit is very popular.

Still exists in PHP 5.3.5. Reproducible with the script above.

This is fixed in 5.4 and HEAD:

Fatal error: Class A contains 1 abstract method and must therefore be declared 
abstract or implement the remaining methods (A::callLate)

Thank you for the report, and for helping us make PHP better.

dup to #60367

Any chance this will get back-ported into older versions? It's still broken in 
PHP 5.3.x up until 5.3.8, which represents a widely distributed range of 
versions.
