What's wrong with these hashtable iteration code?

Hi, I'm trying to iterate through a hash table, But the zend_hash_get_current_key() doesn't seem to move forward: I'm getting duplicate output at the 'fprintf' part. for(zend_hash_internal_pointer_reset_ex(ht, &pos); zend_hash_has_more_elements_ex(ht, &pos) == SUCCESS; zend_hash_move_forward_ex(ht, &pos)) { if (zend_hash_get_current_key (ht, &string_key, &num_key, 0) != HASH_KEY_IS_STRING) continue; fprintf (stderr, "string key: %s\n", string_key); } Any ideas? -- Best Regards, Aaron Lewis - PGP: 0x13714D33 - http://pgp.mit.edu/ Finger Print: 9F67 391B B770 8FF6 99DC D92D 87F6 2602 1371 4D33
