The example in this article describes the method of PHP recording the footprints of search engine spiders visiting the website. Share it with everyone for your reference. The specific analysis is as follows:
Search engine spiders access the website by remotely crawling the page. We cannot use JS code to obtain the spider’s Agent information, but we can use the image tag, so that we can get the spider’s agent information. By analyzing the agent data, we can determine the type, gender and other factors of the spider. We can make statistics by recording it in a database or text.
Database structure:
The following is the quoted content:
# # 表的结构 `naps_stats_bot` # CREATE TABLE `naps_stats_bot` ( `botid` int(10) unsigned NOT NULL auto_increment, `botname` varchar(100) NOT NULL default '', `botagent` varchar(200) NOT NULL default '', `bottag` varchar(100) NOT NULL default '', `botcount` int(11) NOT NULL default '0', `botlast` datetime NOT NULL default '0000-00-00 00:00:00', `botlasturl` varchar(250) NOT NULL default '', UNIQUE KEY `botid` (`botid`), KEY `botname` (`botname`) ) TYPE=MyISAM AUTO_INCREMENT=9 ; # # 导出表中的数据 `naps_stats_bot` # INSERT INTO `naps_stats_bot` VALUES (1, 'Googlebot', 'Googlebot/2.X (+http://www.googlebot.com/bot.html)', 'googlebot', 0, '0000-00-00 00:00:00', ''); INSERT INTO `naps_stats_bot` VALUES (2, 'MSNbot', 'MSNBOT/0.1 (http://search.msn.com/msnbot.htm)', 'msnbot', 0, '0000-00-00 00:00:00', ''); INSERT INTO `naps_stats_bot` VALUES (3, 'Inktomi Slurp', 'Slurp/2.0', 'slurp', 0, '0000-00-00 00:00:00', ''); INSERT INTO `naps_stats_bot` VALUES (4, 'Baiduspider', 'Baiduspider+(+http://www.baidu.com/search/spider.htm)', 'baiduspider', 0, '0000-00-00 00:00:00', ''); INSERT INTO `naps_stats_bot` VALUES (5, 'Yahoobot', 'Mozilla/5.0+(compatible;+Yahoo!+Slurp;+http://help.yahoo.com/help/us/ysearch/slurp)', 'slurp', 0, '0000-00-00 00:00:00', ''); INSERT INTO `naps_stats_bot` VALUES (6, 'Sohubot', 'sohu-search', 'sohu-search', 0, '0000-00-00 00:00:00', ''); INSERT INTO `naps_stats_bot` VALUES (7, 'Lycos', 'Lycos/x.x', 'lycos', 0, '0000-00-00 00:00:00', ''); INSERT INTO `naps_stats_bot` VALUES (8, 'Robozilla', 'Robozilla/1.0', 'robozilla', 0, '0000-00-00 00:00:00', '');
The PHP program is as follows:
The following is the quoted content:
<?php /************************ * NAPS -- Network Article Publish System * ---------------------------------------------- * bot.php * ------------------- * begin : 2004-08-15 * ************************/ /************************ * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License. * ************************/ /************************ * * NAPS产品是自由软件。你可以且必须根据《GNU GPL-GNU通用公共许可证》的相关规定 * 复制、修改及分发NAPS产品。任何以NAPS产品为基础的衍生发行版未必须经过飘飘的授权。 * ************************/ error_reporting(E_ALL & ~E_NOTICE); function get_naps_bot() { $useragent = strtolower($_SERVER['HTTP_USER_AGENT']); if (strpos($useragent, 'googlebot') !== false){ return 'Googlebot'; } if (strpos($useragent, 'msnbot') !== false){ return 'MSNbot'; } if (strpos($useragent, 'slurp') !== false){ return 'Yahoobot'; } if (strpos($useragent, 'baiduspider') !== false){ return 'Baiduspider'; } if (strpos($useragent, 'sohu-search') !== false){ return 'Sohubot'; } if (strpos($useragent, 'lycos') !== false){ return 'Lycos'; } if (strpos($useragent, 'robozilla') !== false){ return 'Robozilla'; } return false; } $tlc_thispage = addslashes($_SERVER['HTTP_USER_AGENT']); //添加蜘蛛的抓取记录 $searchbot = get_naps_bot(); if ($searchbot) { $DB_naps->query("UPDATE naps_stats_bot SET botcount=botcount+1, botlast=NOW(), botlasturl='$tlc_thispage' WHERE botname='$searchbot'"); } ?>
I hope this article will be helpful to everyone’s PHP programming design.
