代码如下:

$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', ' 个结果，', ' 个。 （搜索用时');
    getdetail($google_link, 'google_link', '约有 ', ' 项链接到 '); //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;
}
?>
