<?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);
 //获取本站在百度中的收录数量
?>

<?php 
/** 
* @return array 返回百度的热词数据(数组返回) 
*/ 
function getBaiduHotKeyWord()
{
$templateRss = file_get_contents('http://top.baidu.com/rss_xml.php?p=top10');
if (preg_match('/(.*)<\/table>/is', $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 = "http://www.jb51.net/ *欲查询的域名*/
  $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 = "/(.*)/"; /*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";
?>
