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：

获取百度收录：

<?php
/*
抓取百度收录代码
*/
function baidu($s){
 $baidu="http://www.baidu.com/s?wd=site%3A".$s;
 $site=file_get_contents($baidu);
 //$site=iconv("gb2312", "UTF-8", $site);
 ereg("找到相关网页(.*)篇，", $site,$count);
 $count=str_replace("找到相关网页","",$count);
 $count=str_replace("篇，","",$count);
 $count=str_replace("约","",$count);
 $count=str_replace(",","",$count);
 return $count[0];
}
echo baidu(www.jb51.net);
 //获取脚本之家在百度中的收录数量
?>

获取百度的热词

<?php 
/** 
* @return array 返回百度的热词数据(数组返回) 
*/ 
function getBaiduHotKeyWord()
{
$templateRss = file_get_contents(&#39;http://top.baidu.com/rss_xml.php?p=top10&#39;);
if (preg_match(&#39;/<table>(.*)<\/table>/is&#39;, $templateRss, $_description)) {
$templateRss = $_description [0];
$templateRss = str_replace("&", "&", $templateRss);
}
$templateRss = "<?xml version=1.0 encoding=GBK?>" . $templateRss;
$xml = @simplexml_load_String($templateRss);
foreach ($xml->tbody->tr as $temp) {
if (!empty ($temp->td->a)) {
$keyArray [] = trim(($temp->td->a));
}
}
return $keyArray;
}
print_r(getBaiduHotKeyWord());

这是在网上找的稍微修改了下将下面代码写入php文件
百度收录和百度快照时间

<?php
 $domain = "//www.jb51.net/"; *欲查询的域名*/
 $site_url = &#39;http://www.baidu.com/s?wd=site%3A&#39;;
 $all = $site_url.$domain; /*域名所有收录的网址*/
 $today = $all.&#39;&lm=1&#39;; /*域名今日收录的网址*/
 $utf_pattern = "/找到相关结果数(.*)个/";
 $kz_pattern = "/<span class="g">(.*)</span>/"; /*用以匹配快照日期的字符串*/
 $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*/
 $s0 = @file_get_contents($all); /*将site:www.jb51.net的网页置入$s0字符串中*/
 $s1 = @file_get_contents($today);
 preg_match($utf_pattern,$s0,$all_num); /*匹配"找到相关结果数*个"*/
 preg_match($utf_pattern,$s1,$today_num);
 preg_match($kz_pattern,$s0,$temp);
 preg_match($times,$temp[0],$screenshot);
 if($all_num[1] == "")
  $all_num[1] = 0;
 if($today_num[1] == "")
  $today_num[1] = 0;
 if($screenshot[0] == "")
  $screenshot[0] = "暂无快照";
?>
<html>
 <head>
 <title>Test</title>
 </head>
<body>
 <table>
 <tr>
  <td>日期</td><td>百度收录</td><td>百度今日收录</td><td>百度快照日期</td>
 </tr>
 <tr>
  <td><?php echo date(&#39;m月d日G时&#39;);?> </td><td>
  <?php echo $all_num[1]; ?></td><td>
  <?php echo $today_num[1]; ?></td><td>
  <?php echo $screenshot[0]; ?></td>
 </tr>
 </table>
 <p>百度收录：<a href="<?php echo $all; ?>" target="_blank">
 <?php echo $all_num[1]; ?></a></p>
 <p>百度今日收录：<a href="<?php echo $today; ?>" target="_blank">
 <?php echo $today_num[1]; ?></a></p>
 <p>百度快照日期：<a href="<?php echo $all; ?>">
 <?php echo $screenshot[0]; ?></a></p>
</body>
</html>
