PHP automatically updates the website map every 15 minutes, what is the principle, many novices are not very clear about this, in order to help you solve this problem, the following small series will explain in detail for everyone, there are people who need this can learn, I hope you can harvest.

Recently, I have been working on a short website and wrote my own code. Exercise yourself. In doing html sitemap this, thinking of all the generated short links are displayed, easy to include. I wrote a sitemap.php, and later found that if there is a lot of traffic or too much data in the future, the server burden will be particularly heavy. If there are 10w pieces of data, everyone will index these 10w pieces of data from the database when accessing them. There are 100 people accessing them in one second, and the server simply cannot afford it. Then came the idea of generating html maps.

Due to poor learning skills, there may be some wrong ideas. I wish there were better ways to criticize!

Principle:

Three documents are required:

sitemap.html (a clone of sitemap.php)

sitemap.php (main page, determines page style, etc., complete =sitemap.html)

timeSitemap.php (Generate html pages for updating programs. Monitoring can be set up in the monitoring treasure.)

sitemap.php is a page file, sitemap.html is a clone of sitemap.php. Monitoring treasure sets timeSitemap.php file to generate a site map every 15 minutes. Of course, the frequency is determined according to the monitoring frequency of the monitoring treasure. If the map generation fails, it will return 404, and the monitoring treasure will alarm. sitemap.xml is the same.

The following shared code (with the use of mysql query and other classes for their own simple encapsulated database classes, not shown here):

sitemap.php
