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
