How PHP records the footprints of search engine spiders visiting the website, search engine footprints

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 (6, 'Sohubot', 'sohu-search', 'sohu-search', 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:
