Script in PHP pentru aflare PR
Ce script in PHP ptr aflare PR functional imi recomandati?
Eu am incercat cu scriptul de mai jos, dar nu imi afiseaza ptr toate paginile PR-ul. Cat m-am "invartit" pe net tot de el dau peste tot.
De exemplu merge pentru www.yahoo.com, www.softpedia.com si nu merge ptr www.google.com si ptr www.seopedia.ro.
M-as multumi pana la urma si cu un soft care la o lista de link-uri sa imi dea posibilitatea sa o export, cu PR alaturi. :)
Dupa ce am vazut ca nu merge am descarcat cateva, cel mai bun mi s-a parut PaRaMeter (http://www.cleverstat.com/en/page-rank-monitor-help.htm) insa chiar daca afiseaza ptr Google :D , nici el nu le rezolva pe toate.
Cod:
<?php
if ($url!="") {
include("pagerank.php");
$gpr = new pageRank();
$gpr->printrank("$url");
//display image
echo $gpr->get_pr();

echo "<form method='post' ACTION='tool.php'><input name=url size=100 value='http://www.google.com'><input type=submit value='Check Pagerank'></form>";
