That looks indeed like a small framework. Some remarks:
1. You don't need apache rewriting you can use $_SERVER['PATH_INFO'] and
use url's like:
http:/mysite.com/index.php/news/Dog-Bites-Man
or a page controller:
http:/mysite.com/index.php?site=%2Fnews%2FDog-Bites-Man
2. For the sake of security, put the part that accesses the DB outside
of index.php. It contains an uid and a password.
The scheme will be like this:
in index.php:
include "/path/ouside/webroot/dispatcher.php"
in dispatcher.php:
$conn = new PDO(....);
$stmnt = $conn->prepare(
'SELECT target from dispatch WHERE source = :src');
$stmnt->execute(':src' => $_SERVER['PATH_INFO']);
$row = $stmnt->fetch(PDO::FETCH_ASSOC);
if ($row === false)
// dispatch to 404
;
else
include('/path/outside/webroot/' . $row['target']);
That's all.
