It's a complete scripting. I have added comments to the source code Server-side scripting source code http://forums.xisto.com/no_longer_exists/ /* * convert a string to a 32-bit integer * the string maybe is your webpage's url */function StrToNum($Str, $Check, $Magic)/* * Genearate a hash string from a url */function HashURL($String)/* * genearate a checksum for the hash string */function CheckHash($Hashnum)$C = "<a href=\"https://www.google.com/search?client=navclient-auto&features=Rank:&q=info = "\">Get PageRank</a>";if (isset ($_GET['url'])) { echo $C.$_GET['url'].'&ch='.CheckHash(HashURL($_GET['url'])).$E;} If the scripting get a url parameter from your browser, it will generate a checksum for the url
