写了一个小东西记录baidu和google对于站点的收录情况，现在可以查询了，其实也没什么难度，就是去file下远程文件，然后分析下。
对了貌似查google pr的东西只是file一个地址而已，如此说了就没有什么难度了
下面是代码，对了getdetail函数也可以这样写，用正则去匹配
$wordf = preg_quote($wordf);
$wordb = preg_quote($wordb);
$pagecontent = @preg_replace("//s*$wordf(.+?)$wordb/s*/e", "returndetail('//1', '$type')", $pagecontent);
$pagecontent = @preg_replace("//s*".preg_quote($wordf)."(.+?)".preg_quote($wordb)."/s*/e", "returndetail('//1', '$type')", $pagecontent);
完整代码如下，file取得文件，分析，输出:
< ?php
$seodetail = array();
$domain = !empty($_GET['q']) ? $_GET['q'] : 'www.mycodes.net';
baidudetail($domain);
googledetail($domain);
var_dump($seodetail);
function baidudetail($domain) {
$baidu_site = 'http://www.baidu.com/baidu?word=site%3A' . $domain;
$baidu_link = 'http://www.baidu.com/baidu?word=link%3A' . $domain;
$baidu_domain = 'http://www.baidu.com/baidu?word=domain%3A' . $domain;
getdetail($baidu_site, 'baidu_site', '相关网页', '篇，用时');
getdetail($baidu_link, 'baidu_link', '相关网页', '篇，用时');
getdetail($baidu_domain, 'baidu_domain', '相关网页', '篇，用时');
}
function googledetail($domain) {
$google_site = 'http://www.google.cn/search?hl=zh-CN&q=site%3A' . $domain;
$google_link = 'http://www.google.cn/search?hl=zh-CN&q=link%3A' . $domain;
getdetail($google_site, 'google_site', '</b> 个结果，', ' 个。 （搜索用时');
getdetail($google_link, 'google_link', '<font size=-1>约有 <b>', '</b> 项链接到 <b>');//102
}
function getdetail($url, $type, $wordf, $wordb) {
$pagecontent = @file($url);
$pagecontent = implode('', $pagecontent);
$pagecontent = substr(strstr($pagecontent, $wordf), strlen($wordf));
$pagecontent = substr_replace($pagecontent, '', strpos($pagecontent, $wordb));
returndetail($pagecontent,$type);
}
function returndetail($content,$type) {
global $seodetail;
$seodetail[$type] = empty($content) ? 0 : $content;
}
?>
