This article is about how PHP keeps track of web sites visited by search engine spiders. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

The detailed analysis is as follows:

Search engine spiders visit the website through remote crawling pages to carry out, we can not use JS code to obtain spider Agent information, but we can through the image tag, so that we can get spider agent information, through the analysis of agent information, you can determine the type of spider, gender and other factors, we can record through the database or text statistics.

Database structure:

The following are quoted:

##TABLE STRUCTURE `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 ;##Export data from tables `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', '');
