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

<&#63;php
  $domain = "http://www.jb51.net/ *欲查询的域名*/
  $site_url = 'http://www.baidu.com/s&#63;wd=site%3A';
  $all = $site_url.$domain; /*域名所有收录的网址*/
  $today = $all.'&lm=1′;  /*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";
&#63;>
<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><&#63;php echo date('m月d日G时');&#63;> </td><td>
   <&#63;php echo $all_num[1]; &#63;></td><td>
   <&#63;php echo $today_num[1]; &#63;></td><td>
   <&#63;php echo $screenshot[0]; &#63;></td>
  </tr>
 </table>
  <p>百度收录：<a href="<&#63;php echo $all; &#63;>" target="_blank">
  <&#63;php echo $all_num[1]; &#63;></a></p>
  <p>百度今日收录：<a href="<&#63;php echo $today; &#63;>" target="_blank">
  <&#63;php echo $today_num[1]; &#63;></a></p>
  <p>百度快照日期：<a href="<&#63;php echo $all; &#63;>">
