如果大家稍加仔細看一下就能發現一個問題,我們下面幾個抓取百度收錄或快照或熱詞的程序中都有一個函數file_get_contents(),他是php采集網頁常用的哦。
- <?
- /*
- 抓取百度收錄代碼
- */
- 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("找到相關網頁(.*)篇,", $site,$count);
- $count=str_replace("找到相關網頁","",$count);
- $count=str_replace("篇,","",$count);
- $count=str_replace("約","",$count);
- $count=str_replace(",","",$count);
- return $count[0];
- }
- echo baidu(www.hzhuti.com); //獲取好主題在百度中的收錄數量
- ?>
獲取百度的熱詞
- <?php
- /**
- * * @user 小杰
- * @return array 返回百度的熱詞數據(數組返回)
- */
- 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());
- <?php
- $domain = “http://m.survivalescaperooms.com/nokia/5230/ *欲查詢的域名*/
- $site_url = ‘http://m.survivalescaperooms.com/s?wd=site%3A’;
- $all = $site_url.$domain; /*域名所有收錄的網址*/
- $today = $all.’&lm=1′; /*域名今日收錄的網址*/
- $utf_pattern = “/找到相關結果數(.*)個/”;
- $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}/”; /*匹配快照日期的正則表達式,如:2011-8-4*/
- $s0 = @file_get_contents($all); /*將site:www.Vevb.net的網頁置入$s0字符串中*/
- $s1 = @file_get_contents($today);
- preg_match($utf_pattern,$s0,$all_num); /*匹配”找到相關結果數*個”*/
- preg_match($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] = “暫無快照”;
- ?>
- <html>
- <head>
- <title>Test</title>
- </head>
- <body>
- <table>
- <tr>
- <td>日期</td><td>百度收錄</td><td>百度今日收錄</td><td>百度快照日期</td>
- </tr>
- <tr>
- <td><?php echo date(‘m月d日G時’);?> </td><td><?php echo $all_num[1]; ?></td><td><?php echo $today_num[1]; ?></td><td><?php echo $screenshot[0]; ?></td>
- </tr>
- </table>
- <p>百度收錄:<a href=”<?php echo $all; ?>” target=”_blank”><?php echo $all_num[1]; ?></a></p>
- <p>百度今日收錄:<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>
上面的方法未經過嚴格考慮,如果服務器不支持file_get_contents函數我們就無法操作了,所以還可以利用curl操作,這個更方便可以模仿用戶哦。
