This article describes the method of PHP recording search engine spiders accessing website footprints. Share it for your reference. The specific analysis is as follows:
Search engine spiders visit websites by remotely crawling pages. We cannot use JS code to obtain spider agent information, but we can use image tags so that we can get spider agent information. Through the analysis of agent data, we can determine the type, gender and other factors of the spider. We can record it through database or text to conduct statistics.
Database structure:
The following is the quoted content:
# # 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 table `naps_stats_bot`# INSERT INTO `naps_stats_bot` VALUES (1, 'Googlebot', 'Googlebot/ (+/)', 'googlebot', 0, '0000-00-00 00:00:00', ''); INSERT INTO `naps_stats_bot` VALUES (2, 'MSNbot', 'MSNBOT/0.1 (/)', '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+(+/search/)', 'baiduspider', 0, '0000-00-00 00:00:00', ''); INSERT INTO `naps_stats_bot` VALUES (5, 'Yahoobot', 'Mozilla/5.0+(compatible;+Yahoo!+Slurp;+/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/', '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', '');
