<p>本文实例讲述了php获取百度收录、百度热词及百度快照的方法。分享给大家供大家参考。具体如下：</p>
<p>获取百度收录：</p>
<p><?php<br />
/*<br />
抓取百度收录代码<br />
*/<br />
function baidu($s){<br />
$baidu="http://www.baidu.com/s?wd=site%3A".$s;<br />
$site=file_get_contents($baidu);<br />
//$site=iconv("gb2312", "UTF-8", $site);<br />
ereg("找到相关网页(.*)篇，", $site,$count);<br />
$count=str_replace("找到相关网页","",$count);<br />
$count=str_replace("篇，","",$count);<br />
$count=str_replace("约","",$count);<br />
$count=str_replace(",","",$count);<br />
return $count[0];<br />
}<br />
echo baidu(www.jb51.net);<br />
//获取帮客之家在百度中的收录数量<br />
?><br />
获取百度的热词</p>
<p><?php<br />
/**<br />
* @return array 返回百度的热词数据(数组返回)<br />
*/<br />
function getBaiduHotKeyWord()<br />
{<br />
$templateRss = file_get_contents('http://top.baidu.com/rss_xml.php?p=top10');<br />
if (preg_match('/<table>(.*)<\/table>/is', $templateRss, $_description)) {<br />
$templateRss = $_description [0];<br />
$templateRss = str_replace("&", "&", $templateRss);<br />
}<br />
$templateRss = "<?xml version=1.0 encoding=GBK?>" . $templateRss;<br />
$xml = @simplexml_load_String($templateRss);<br />
foreach ($xml->tbody->tr as $temp) {<br />
if (!empty ($temp->td->a)) {<br />
$keyArray [] = trim(($temp->td->a));<br />
}<br />
}<br />
return $keyArray;<br />
}<br />
print_r(getBaiduHotKeyWord());<br />
这是在网上找的 稍微修改了下 将下面代码写入php文件<br />
百度收录和百度快照时间</p>
<p><?php<br />
$domain = "http://www.bkjia.com/ *欲查询的域名*/<br />
$site_url = 'http://www.baidu.com/s?wd=site%3A';<br />
$all = $site_url.$domain; /*域名所有收录的网址*/<br />
$today = $all.'&lm=1′; /*域名今日收录的网址*/<br />
$utf_pattern = "/找到相关结果数(.*)个/";<br />
$kz_pattern = "/<span class="g">(.*)</span>/"; /*用以匹配快照日期的字符串*/<br />
$times = "/d{4}-d{1,2}-d{1,2}/"; /*匹配快照日期的正则表达式，如:2011-8-4*/<br />
$s0 = @file_get_contents($all); /*将site:www.jb51.net的网页置入$s0字符串中*/<br />
$s1 = @file_get_contents($today);<br />
preg_match($utf_pattern,$s0,$all_num); /*匹配"找到相关结果数*个"*/<br />
preg_match($utf_pattern,$s1,$today_num);<br />
preg_match($kz_pattern,$s0,$temp);<br />
preg_match($times,$temp[0],$screenshot);<br />
if($all_num[1] == "")<br />
$all_num[1] = 0;<br />
if($today_num[1] == "")<br />
$today_num[1] = 0;<br />
if($screenshot[0] == "")<br />
$screenshot[0] = "暂无快照";<br />
