Did the overloading API in PHP4 actually ever work? I have done some
simple stuff with it in the past, but I tried using it for something real
today and it is falling over. I have a very simple example extension
which illustrates it. See http://lerdorf.com/ovl.tar.gz
For the lazy, here is the meat of it. The problem is in my set function
which looks like this:
int _ovl_property_set(zend_property_reference *prop_ref, zval *value) {
zend_llist_element *element = prop_ref->elements_list->head;
zval overloaded_property = ((zend_overloaded_element *)(element->data))->element;
zval_add_ref(&value);
add_property_zval(prop_ref->object, Z_STRVAL(overloaded_property), value);
return SUCCESS;
}
If I do:
$obj->foo = array(1,2,3);
Then the zval value that gets passed to my set function is messed up. If
instead I do:
$tmp = array(1,2,3);
$obj->foo = $tmp;
Then everything is fine.
The http://lerdorf.com/ovl.tar.gz tarball has a full self-contained
example of the problem if someone wouldn't mind having a look.
