Help - Merging Resource into a call_function array

Can someone help me out with this one, - I'm sure that I've not acheived what I was aiming at - adding the Resource, myresource to the array prior to calling the callback function.... the code below is from the url_request callback wrapper for gtkhtml - if this works - you can build a working web browser/editor in php.. regards alan static void php_gtk_html_url_request_callback (GtkHTML *html, const char *url, GtkHTMLStream *gs, zval* callback_data) { zval *myresource = NULL; zval *retval = NULL; zval **callback = NULL, **extra = NULL; zval **callback_filename = NULL, **callback_lineno = NULL; zval ***args, *params; char *callback_name; TSRMLS_FETCH(); zend_hash_index_find(Z_ARRVAL_P(callback_data), 0, (void **)&callback); zend_hash_index_find(Z_ARRVAL_P(callback_data), 1, (void **)&extra); zend_hash_index_find(Z_ARRVAL_P(callback_data), 2, (void **)&callback_filename); zend_hash_index_find(Z_ARRVAL_P(callback_data), 3, (void **)&callback_lineno); if (!php_gtk_is_callable(*callback, 0, &callback_name)) { php_error(E_WARNING, "Unable to call ctree callback '%s' specified in %s on line %d", callback_name, Z_STRVAL_PP(callback_filename), Z_LVAL_PP(callback_lineno)); efree(callback_name); return; } params = php_gtk_build_value("(s)", url); ZEND_REGISTER_RESOURCE(myresource, gs, le_gtkhtmlstream); zend_hash_next_index_insert(Z_ARRVAL_P(params), (zval *) &myresource, sizeof(zval *), NULL); if (extra) php_array_merge(Z_ARRVAL_P(params), Z_ARRVAL_PP(extra), 0); args = php_gtk_hash_as_array(params); call_user_function_ex(EG(function_table), NULL, *callback, &retval, zend_hash_num_elements(Z_ARRVAL_P(params)), args, 0, NULL TSRMLS_CC); if (retval) zval_ptr_dtor(&retval); efree(args); zval_ptr_dtor(&params); }
