Not a bug, you need to declare the method 'bar' as static.

I should have also mentioned that calling an instance method in a static
context
does not generate an error, unless the called method has any references to
$this
(which of course is not in scope), in which case a fatal error occurs. This
can
be a little tricky to track down, and so would be preferable if instance
methods
were simply not in scope for static contexts.

With PHP 5.3.2, if the instance method bar() is *not* public, and
__callStatic()
*is*, __callStatic() will be invoked, because bar() won't be in scope.
Unfortunately, this seems like a horribly hacked work-around. Ideally, public
instance methods should not be in scope from a static context, so
__callStatic()
will be called instead.

Description:
------------
A static call to Foo::bar() does not invoke __callStatic() if an
instance method bar() exists.
One reason you might want this is to convert static calls to Foo::bar()
to the equivalent operation on a singleton:
public static function __callStatic($name, $args) {
$obj = self::getInstance();
return call_user_func_array(array($obj, $name), $args);
}
In the sample code below, __callStatic() is not invoked even though the
caller has deliberately initiated a static call.
Reproduce code:
---------------
<?php
class Foo {
public static function __callStatic($name, $args) {
echo "In __callStatic()\n";
}
public function bar() {
echo "In bar()\n";
}
}
echo Foo::bar();
Expected result:
----------------
In _callStatic()
Actual result:
--------------
PHP Strict Standards: Non-static method Foo::bar() should not be called
statically in /mnt/hgfs/workspace/scratch/wart1.php on line 15
