RE: [PHP-DEV] call_user_function()
What happened with this in the end.
I have a case where call_user_function needs to call a class function
without me having to instantiate a dummy object first.

[PHP-DEV] call_user_function()
I was wondering why call_user_function doens't handle calling methods of objects for an incomplete_class_entry. call_user_function(NULL, incomplete_class, function_name, return, 0, NULL); i took a look at the code and it assumes that the function that you want to call is in the class_entry.function_table... is this by design or did someone just not want to implement call_user_function and call the callback handler if there were no builtin functions... - Brad __ Do You Yahoo!?

Re: [PHP-DEV] call_user_function()
well... i hacked up a function to handle this...
does anyone wanna look at my code and maybe possible include it with
call_user_function
int my_call_user_function(HashTable *function_table, zval **object_pp, zval
*function_name, zval *retval_ptr, int param_count, zval *params[] TSRMLS_DC)
{
if(call_user_function(function_table, object_pp, function_name, retval_ptr,
param_count, params TSRMLS_CC) == FAILURE)
{
if(Z_OBJCE_PP(object_pp)-handle_function_call != NULL)
{
zend_overloaded_element overloaded_element;
zend_property_reference property_reference;
zend_function_state function_state;
zend_function_state *original_function_state_ptr;
int i;
overloaded_element.element = *function_name;
overloaded_element.type = OE_IS_METHOD;
property_reference.object = *object_pp;
property_reference.type = BP_VAR_NA;
property_reference.elements_list = (zend_llist *)
emalloc(sizeof(zend_llist));
zend_llist_init(property_reference.elements_list,
sizeof(zend_overloaded_element), NULL, 0);
zend_llist_add_element(property_reference.elements_list,
overloaded_element);
//Build argument stack
for(i = 0;i param_count;i++)
zend_ptr_stack_push(EG(argument_stack), params[i]);
zend_ptr_stack_n_push(EG(argument_stack), 2, (void *)
param_count, NULL);
EG(function_state_ptr) = function_state;
Z_OBJCE_PP(object_pp)-handle_function_call(param_count,
retval_ptr,
*object_pp, 1 TSRMLS_CC, property_reference);
EG(function_state_ptr) = original_function_state_ptr;
zend_llist_destroy(property_reference.elements_list);
efree(property_reference.elements_list);
zend_ptr_stack_clear_multiple(TSRMLS_C);
return SUCCESS;
}
}
}
i know there's some things wrong with it but... it does work...
like function_state will be garbage.. i didn't know what/how to fill that
structure with.
