PHP Zend Engine Extension and static methods

Question

On writing an extension for php (5.3) i want to access the zend_class_entry pointer on a static method.

On non static methods i can use the getThis() macro and within Z_OBJCE_P macro like this:

zend_class_entry ce* = Z_OBJCE_P(getThis());

Now the problem: on static methods the getThis() macro returns a null pointer, so i can not use the Z_OBJCE_P macro.

Has anyone a solution for me to access the zend_class_entry from a static method??

it is really interesting: on static methods you can access the scope like this

zend_class_entry* ce = 0L;
if (EG(called_scope)) {
    ce = EG(called_scope);
} else if (!EG(scope))  {
    ce = EG(scope);
}

the EG Macro access a lot of global and context specific variables, also the calling scope, the calling class of the static method.

Note the called scope is not the same as the (calling) scope, the first is related to LSB, the second is probably what you want.
