Overloaded class registration

Hello Evan,

what you do is irrelevant you need to define the method signature.
See example from Zend/zend_interfaces.c:
static
ZEND_BEGIN_ARG_INFO(arginfo_arrayaccess_offset, 0)
ZEND_ARG_INFO(0, offset)
ZEND_END_ARG_INFO();

static
ZEND_BEGIN_ARG_INFO(arginfo_arrayaccess_offset_value, 0)
ZEND_ARG_INFO(0, offset)
ZEND_ARG_INFO(0, value)
ZEND_END_ARG_INFO();

zend_function_entry zend_funcs_arrayaccess[] = {
ZEND_ABSTRACT_ME(arrayaccess, offsetExists, arginfo_arrayaccess_offset)
ZEND_ABSTRACT_ME(arrayaccess, offsetGet, arginfo_arrayaccess_offset)
ZEND_ABSTRACT_ME(arrayaccess, offsetSet, arginfo_arrayaccess_offset_value)
ZEND_ABSTRACT_ME(arrayaccess, offsetUnset, arginfo_arrayaccess_offset)
{NULL, NULL, NULL}
};

Hello Evan,

your implementation is wrong, you need to specify the arguments to
__get/__set.

Thanks for the reply, but can you be a bit more specific? I'm already
specifying num_args and required_num_args (the former of which is what is
checked in zend_check_magic_method_implementation()). Setting arg_info seems
to have no effect. Here's the code I used to try setting arg_info (apologies
if it wraps) for the __set method:

    fe_set.type = ZEND_INTERNAL_FUNCTION;
    fe_set.handler = ZEND_FN(fannOO___set);
    fe_set.function_name = NULL;
    fe_set.scope = NULL;
    fe_set.fn_flags = 0;
    fe_set.prototype = NULL;
    fe_set.num_args = 2;
    fe_set.required_num_args = 2;
    fe_set.arg_info = ecalloc(fe_set.num_args, sizeof(zend_arg_info));
    fe_set.pass_rest_by_reference = 0;

    fe_set.arg_info[0].name = one;
    fe_set.arg_info[0].name_len = strlen(one);
    fe_set.arg_info[0].class_name = le_fann_name;
    fe_set.arg_info[0].class_name_len = strlen(le_fann_name);
    fe_set.arg_info[0].allow_null = 0;
    fe_set.arg_info[0].pass_by_reference = 0;
    fe_set.arg_info[0].return_reference = 0;
    fe_set.arg_info[0].required_num_args = fe_set.required_num_args;

    fe_set.arg_info[1].name = two;
    fe_set.arg_info[1].name_len = strlen(two);
    fe_set.arg_info[1].class_name = le_fann_name;
    fe_set.arg_info[1].class_name_len = strlen(le_fann_name);
    fe_set.arg_info[1].allow_null = 0;
    fe_set.arg_info[1].pass_by_reference = 0;
    fe_set.arg_info[1].return_reference = 0;
    fe_set.arg_info[1].required_num_args = fe_set.required_num_args;

best regards

Hi everyone,

I noticed recently that both of my extensions (Panda and FANN, both in
PECL) emit error messages when their __get() and __set() methods are
registered. The problem seems to be that fptr.common->num_args is always
0 in zend_check_magic_method_implementation(), regardless of what I set
them to prior to registration.

The functions still work perfectly, and valgrind doesn't complain.
There's just an incredibly annoying error message every time. It's
entirely possible (if not probable) that it's my code that's wrong, not
ZE2, but I can't for the life of me figure it out.

The pertinant portion of the code is based on the SOAP extension. The
source code for the fann extension is at

http://cvs.sourceforge.net/viewcvs.py/checkout/fann/fannphp/fann.c?rev=

1.13

I tried pecl-dev last week, and the only suggestion I got was using the
read_property and write_property callbacks instead of the __get() and
__post() methods, but I don't really think that's an option. The thread
is at http://marc.theaimsgroup.com/?l=pecl-dev&m=110012046408453&w=2

Thanks.
