Бележки

Забележка: Performance
Speed-wise, the function is identical to mysql_fetch_array(), and almost as quick as mysql_fetch_row() (the difference is insignificant).

Забележка: mysql_fetch_object() is similar to mysql_fetch_array(), with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names).

Забележка: Имената на полетата, връщани от тази функция, са чувствителни към регистъра.

Забележка: Тази функция установява NULL полетата със стойността null; в PHP.
