Bene.. la notte porta consigli quando non si ha sonno... per cui vado a presentare il nuovo progetto: "
NamaPR e' una classe scritta in PHP che permette tramite una semplice funzione avere il PR (Pagerank) di un dominio.
Per il momento non ho ancora passato lo script a classe effettiva perche' sti' facendo delle prove se usare la classe cosi':
echo NamaPR('www.namaless.com');
echo new NamaPR('www.namaless.com');
Aspettavo proprio di pubblicarlo qui.. 
Per quanto riguarda la classe basta salvare il tutto in un file tipo "NamaPR.class.php" e nel solito posto creare un file "index.php", nel file "NamaPR.class.php" ci mettete questo codice:

// richiama la classe NamaPR
require_once('NamaPR.class.php');

Cosi' per vedere il pr di un dominio bastera' usare il link "http://www.sito.it/index.php?url=www.namaless.com" e verra' restituito in numero il pr dell'url.
