There's a very neat syntax you can use that I learned about a couple of months ago that does not rely on a temporary variable. Here's an example where I use a POST variable to load a specific class:

In your specific case though, you would be able to solve it by using PDO. It has a fetch mode that allows the first column's value to be the class the row instantiates into.

$sth->fetch(PDO::FETCH_CLASS | PDO::FETCH_CLASSTYPE);
