Assuming you're using MySQL,
mysql_fetch_row returns a row as an enumerated array
mysql_fetch_array returns an enumerated or associative array
mysql_fetch_object returns an object.
In each case, you do not need to know in advance how many fields will be
returned. And if you use the associative array or the object you can get
at the names of the fields as well.
Does this answer your question?
