Those are the ones you want, plus zend_hash_get_current_data.

The only difference is that zend_hash_find is smart about numeric
string indexes.  For example, if the array has a key with the integer
value 4, doing zend_hash_find after the string key "4" will still find
it.  zend_hash_quick_find doesn't do this.

I don't think so? :-)
