Best practice for filing of abstract class and subclasses?
<p>I was wondering what is the best (and real-word) practice for doing an abstract class and subclasses in PHP when it comes to filing.</p>

<p>I have <code>abstract class games</code>, and I was wondering if I should put the subclasses into separate files and <code>require_once('games.class.php');</code> for separate files or just have each subclass in the <code>abstract class games</code> file?</p>

<p>Thanks!</p>
