这篇文章主要介绍了php获取百度收录、百度热词及百度快照的方法,实例分析了php抓取百度页面及对应字符串分析的技巧,非常具有实用价值,需要的朋友可以参考下
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.vevb.com);
- //获取武林网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('http://top.baidu.com/rss_xml.php?p=top10');
- if (preg_match('/<table>(.*)<//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 $temp) {
- if (!emptyempty ($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.vevb.com/ *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 = "/<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.vevb.com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('m月d日G时');?> </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>
希望本文所述对大家的php程序设计有所帮助。
