Declaring php-class static member functions from within C/C++

If I define/declare php class methods via:

INIT_CLASS_ENTRY(ce, phpclassname, myclassmethods);

where myclassmethods is defined as eg:

function_entry myclass::myclassmethods[]
= {
PHP_ME(myclass, __construct, arginfo_Guid__construct, ZEND_ACC_PUBLIC)
PHP_ME(myclass, getValue, NULL, ZEND_ACC_PUBLIC)
};

then getValue is a member function of an instantiated object,

Unsurprisingly, attempting to call myclass::getValue() therefore generates a:

"Non-static method myclass::getValue() cannot be called statically" error,
even where no dependency on the object (via getThis()) is required.

How then can I inform zend/php of my intent to supply a static member
function, such that I can call for example myclass::somestaticfunc()

I can clearly create global functions, viz: myclass_somestaticfunc() but these
would all apparently need to be declared in the module function entry.

A neater solution would be to declare static member functions pertinent to the
class, either by flagging them as static, or suppling a second function_entry
to a 'static member functions *' in class_entry.

Php clearly tolerates static member functions in its own php-defined classes.

Is there a declaration mechanism available to declare them from within C/C++?

Cheers,

Andrew.
