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 $count[0];}echo baidu(www.yinxi.net); //获取网页设计在百度中的收录数量?>获取百度的热词
<?php /** * @return array 返回百度的热词数据(数组返回) */ function getBaiduHotKeyWord(){$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 $temp) {if (!empty ($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 = "//www.yinxi.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 = "/<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.yinxi.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";?><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。
