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 $count[0];}echo baidu(www.jb51.net); //获取脚本之家在百度中的收录数量?>获取百度的热词
<?php /** * @return array 返回百度的热词数据(数组返回) */ function getBaiduHotKeyWord(){$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 = "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/";$kz_pattern = "/<span class="g">(.*)</span>/"; /*用以匹配快照日期的字符串*/$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.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";?><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。
