Notas

Note: Performance

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

Note:

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).

Note: Los nombres de los campos devueltos por esta función son sensibles a mayúsculas y minúsculas.

Note: Esta función define campos NULOS al valor NULL de PHP.
