A simple addition:
You can get rid of the boring <html><head></head> ... stuff by changing
the above setup like:
ob_start();
if ($row === false)
// dispatch to 404
;
else
include('/path/outside/webroot/' . $row['target']);
$contents = ob_get_clean();
include "mytemplate.php"
Where mytemplate can put an <?php echo $contents; ?> in the right place.
All major frameworks use this trick.
