php 查询百度与google收录情况的实现代码

用php来查询百度或google的收录情况，其实并不复杂，只需要file下远程文件，然后分析相关数据即可。

以下是收录查询核心代码，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(.+?)$wordbs*/e", "returndetail('1', '$type')", $pagecontent);
$pagecontent = @preg_replace("/s*".preg_quote($wordf)."(.+?)".preg_quote($wordb)."s*/e", "returndetail('1', '$type')",
 $pagecontent);

完整代码：
 

<?php
/**
* 查询百度与google的收录情况
* by www.jb200.com
*/
$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;
}
?>
