For queries, instead of:

PHP Code:

$result = mysql_query($query);
$num = mysql_numrows($result); 


Do this:

PHP Code:

$result = $db->query_read($query);
$num = $db->num_rows($result); 


I have found the best thing to do to learn this stuff is to take a look at the articles and also download a few modifications and see how the developer did things there.
