Summary: __callStatic from a derived class object context
calls __call instead
Status: Not a bug
Type: Bug
Package: Reflection related
Operating System: Windows 7 Prof.

New Comment:
It is a static call if You use an empty proxy class like below. The only
difference in scope is, that MyProxyClass is not directly in the hierachy tree
above the calling method's class. Please explain why this is intended.
class MyProxyClass extends MyBaseClass { //empty }
class MyDerivedClass extends MyBaseClass {
function someAction()
{
return MyProxyClass::Foo();
}
}

if there is a calling scope, then :: is not a static call.
if there is no calling scope, then :: is a static call.
the key point is the calling scope, not the "::" .
thanks

You are mistaken. MyBaseClass::Foo() is not necessarily a static call. Namely,
if $this is of type MyBaseClass or a subclass thereof and there's no explicit
static method MyBaseClass::Foo(), then MyBaseClass::Foo() is an instance call.

Excuse me, but how exactly does parent::Foo() come into the discussion?
The test code is calling MyBaseClass::Foo(), which clearly is a static call.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
This is due to the way calls to parent::foo() and such are handled, these look
like static calls but in fact aren't.

Description:
------------
If You define both the magic function for static and dynamic calls for a class
and
then call a static function from a derivate's method, not the static but the
dynamic magic function is called.
Test script:
---------------
<?php
class MyBaseClass {
public static function __callStatic($what, $args)
{
return 'static call';
}
public function __call($what, $args)
{
return 'dynamic call';
}
}
class MyDerivedClass extends MyBaseClass {
function someAction()
{
//here I call a base class' static function
//it returns "dynamic call" instead of "static call"
return MyBaseClass::Foo();
}
}
$bar = new MyDerivedClass();
echo $bar->someAction();
?>
Expected result:
----------------
static call
Actual result:
--------------
dynamic call
------------------------------------------------------------------------
