PHP Method for recording the website footprint of search engine spider access, search engine footprint

This example describes how to record the website footprint of a search engine spider in PHP. Share it with you for your reference. The specific analysis is as follows:

The search engine crawlers access websites by capturing pages remotely. We cannot use JS Code to obtain the Agent information of the spider, but we can use the image Tag, in this way, we can obtain the agent data of the Spider. By analyzing the agent data, we can determine the types, gender, and other factors of the spider, we can record statistics through databases or text.

Database Structure:

Reference content is as follows:

# 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 '2017-00-00 00:00:00 ', 'botlasturl' varchar (0000) not null default '', unique key 'botid' ('bo Tid'), KEY 'botname' ('botname') TYPE = MyISAM AUTO_INCREMENT = 9; # export data in the table 'naps _ stats_bot '# insert into 'naps _ stats_bot' VALUES (1, 'googlebot ', 'googlebot/2.X (+ http://www.googlebot.com/bot.html )', 'bot bot ', 0, '2014-00-00 00:00:00', ''); insert into 'naps _ stats_bot 'VALUES (2, 'msnbot ', 'msnbot/0.1 (http://search.msn.com/msnbot.htm) ', 'msnbot', 0, '2017-00-00 00:00:00 ', ''); insert into 'naps _ st Ats_bot 'values (3, 'inktomi slurp', 'slurp/123456', 'slurp', 0, '2017-00-00 00:00:00 ',''); insert into 'naps _ stats_bot 'VALUES (4, 'baidider ider', 'baidider ider + (+ http://www.baidu.com/search/spider.htm) ', 'baidider ider', 0, '2017-00-00 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) ', 'slup', 0, '2017-00-00 00:00:00', ''); insert into 'naps _ stats_bot 'VALUES (6, 'sohubot ', 'sohu-search', 'sohu-search', 0, '2017-00-00 00:00:00 ',''); insert into 'naps _ stats_bot 'VALUES (7, 'lycos', 'lycos/x. x', 'lycos ', 0, '2014-00-00 00:00:00', ''); insert into 'naps _ stats_bot 'VALUES (8, 'robozilla ', 'robozilla/123456', 'robozilla ', 0, '2017-00-00 00:00:00 ','');

The PHP program is as follows:
