PHP: mysql_fetch_object - Manual

PHP: mysql_fetch_array - Manual

very similar.

returning an object is usually more effective if you are used to Object oriented language.
In my opinion it is easier to write code for objects, especially if you are doing complicated coding.

but if you are just doing basic stuff, an array may is easier.
