This is the code: zval *args[3], *func, *retval; MAKE_STD_ZVAL(func); MAKE_STD_ZVAL(retval); MAKE_STD_ZVAL(args[0]); MAKE_STD_ZVAL(args[1]); MAKE_STD_ZVAL(args[2]); ALLOC_HASHTABLE(args[2]); // creates hash and fills zend_hash_init(args[2], 0, NULL, NULL, 0); g_hash_table_iter_init (&iter, m->params); while (g_hash_table_iter_next (&iter, &key, &value)) { zend_hash_add(args[2], key, strlen(key), value, strlen(value), NULL); } ZVAL_STRING(args[0], estrdup(m->sender), 0); ZVAL_STRING(args[1], estrdup(m->cmd), 0); ZVAL_STRING(func, estrdup(handler), 0); if (call_user_function(EG(function_table), NULL, func, retval, 3, args TSRMLS_CC) == FAILURE) { g_debug("error calling method: %s", handler); } zval_dtor(retval); zval_dtor(func); zval_dtor(args[0]); zval_dtor(args[1]); zend_hash_destroy(args[2]); FREE_HASHTABLE(args[2]); I suppose that the problem is the conversion between the Hash and the zval, but I don't know how to do it. Thanks in advance :) regards --- ## #40377 — Marcus Boerger — 2008-09-08T21:55:04+00:00 URL: https://externals.io/message/40348#40377 · In reply to: #40348 Hello mr, Monday, September 8, 2008, 6:58:19 PM, you wrote: > Hi all, > I'm having problems passing an array to the function call_user_function as > parameter.

I have changed the code, and it works with strings and even with arrays, but not with hashes: Am I missing something? zval *hash; zval **args[2], *func, *retval; zval *str; MAKE_STD_ZVAL(retval); MAKE_STD_ZVAL(func); ZVAL_STRING(func, estrdup(handler), 0); MAKE_STD_ZVAL(str); ZVAL_STRING(str, estrdup(m->sender), 0); MAKE_STD_ZVAL(hash); ALLOC_HASHTABLE(hash); zend_hash_init(hash, 0, NULL, NULL, 1); g_hash_table_iter_init (&iter, m->params); while (g_hash_table_iter_next (&iter, &key, &value)) { zend_hash_add(hash, g_strdup(key), strlen(key), g_strdup(value), strlen(value), NULL); } args[0] = &hash; args[1] = &str; if (call_user_function_ex(EG(function_table), NULL, func, retval, 2, &args, 0, `NULL` TSRMLS_CC) == FAILURE) { g_debug("error calling method: %s", handler); } ...

I had confused the functions hash_* with the funtions array_*. This works: MAKE_STD_ZVAL(hash); array_init(hash); g_hash_table_iter_init (&iter, m->params); while (g_hash_table_iter_next (&iter, &key, &value)) { add_assoc_string(hash, key, value, 0); } Thanks for your help and your patience :) AntP 2008/9/10 mr esnafrao > Thanks for your response, but I'm unable to make it work.
