Hazır site istatistikleri üzerine birşeyler yazıyorken google pagerank sorgulama scriptini sizlerle paylaşayım dedim ,site analiz bölümünde pagerank’ı bununla bulduruyorum ,pr 0 olunca hiçbirşey yazmıyordu o yüzden bir if ekledim oraya siz isterseniz düzenlersiniz.

if($pos === false){} else{
$pagerank = substr($data, $pos + 9);
return $pagerank;
