Funzione che restituisce il pagerank
Ho trovato questo script http://www.tapouillo.com/firefox_extension/sourcecode.txt ma non ho capito come si usa passando come parametro get url=http://www.google.it mi restituisce url: http://www.google.it Checksum =2.0.114: 64249338711 manca poco mi sa ma come si ricava il numerino del PR? grazie (il post ha problemi)

ti posto il codice che uso io...

$a = ($a>>$b);

no non ho toccato neinte..il nome della pagina è pr invece di page_rank ma non credo che influisca
sono su server aruba

no il nome nn influisce...hai un server locale?? se si provalo lì..perchè se ti funziona significa che cè qualcosa che nn va su Aruba...
