Note

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

Nota: 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).

Nota: I nomi dei campi restituiti da questa funzione sono case-sensitive.

Nota: Questa funzione imposta i campio NULL al valore PHP null.
