mysqli and arrays

Hello freaks.

Im new to OOP and I'm just starting to practice using this mysqli object. What I want to do is fetch a bunch of results and store them in an array and what I've done is this

 
$result = $db->query("SELECT * FROM `stuff`");
while($row = $result->fetch_assoc()){
$stuff[] = $row;
}

and I can't help but wonder if there is a more efficient way of doing this, for example without looping ?
