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”;
?>
