本文介绍下，用php获取百度收录情况，以及百度快照时间的一段代码，有需要的朋友，作个参考吧。

用php代码实现查询百度收录情况与百度快照时间。

代码：

<?php
//查询百度收录
//查询百度快照
 $domain = “jbxue.com/*待查询域名*/
 $site_url = ‘http://www.baidu.com/s?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.ninthday.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”;
?>
