我有一个脚本可以为输入的 URL 提取 Google Pagerank。
我尝试编辑脚本，以便您可以粘贴一个 URL 列表，而不是只能放入 3 个 URL。
不幸的是，当我在其中添加一些 URL 时，它们只是将它们彼此相邻，并且不显示 Pagerank。
如果你想测试它并看到你可以在这里找到它：http: //php-playground.co.cc/testdir/pagerank.php
（人们一直在报告该 URL 上的病毒，但这只是因为它是一个 co.cc 域，如果您担心，请不要点击 :)
这是代码：
<?php
//If the form was submitted
if(isset($_GET['url[]'])){
//Put every new line as a new entry in the array
$url = explode("\n",trim($_POST["url[]"]));
}
echo "$url";
?>
<?php
function fetch_google_page_rank($url) {
$url = strstr($url,"http://")? $url:"http://".$url;
$fp = fsockopen("toolbarqueries.google.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET /tbr?client=navclient- auto&ch=".CheckHash(HashURL($url))."&features=Rank&q=info:".$url."&num=100&filter=0 HTTP/1.1\r\n";
$out .= "Host: toolbarqueries.google.com\r\n";
$out .= "User-Agent: Mozilla/4.0 (compatible; GoogleToolbar 2.0.114-big; Windows XP 5.1)\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
$data = fgets($fp, 128);
$pos = strpos($data, "Rank_");
if($pos === false){} else{
$pagerank = substr($data, $pos + 9);
}
}
fclose($fp);
return (int)$pagerank;
}
}
