PR值是google衡量網站的重要標準之一,根據google提供的結果擷取pr值,如:
http://toolbarqueries.google.com.hk/tbr?client=navclient-auto&features=Rank:&q=info:phpddt.com&ch=8fabc62ea
<?php/**功能:對URL進行編碼*參數說明:$web_url 網站URL,不包含"http://"*/function HashURL($url){ $SEED = "Mining PageRank is AGAINST GOOGLE’S TERMS OF SERVICE. Yes, I’m talking to you, scammer."; $Result = 0x01020345; for ($i=0; $i<strlen($url); $i++) { $Result ^= ord($SEED{$i%87}) ^ ord($url{$i}); $Result = (($Result >> 23) & 0x1FF) $Result << 9; } return sprintf("8%x", $Result);}/**功能:根據google提供的pr查詢介面擷取pagerank*參數說明:$domain 網站網域名稱,不包含"http://"*/function pagerank($domain){ $StartURL = "http://toolbarqueries.google.com/tbr?client=navclient-auto&features=Rank:&q=info:"; $GoogleURL = $StartURL.$domain. '&ch='.HashURL($domain); echo $GoogleURL.'<br>'; $fcontents = file_get_contents("$GoogleURL"); $pagerank = substr($fcontents,9); if (!$pagerank) return "0";else return $pagerank;}echo pagerank("phpddt.com");?>
