Pagination, search, and sorting have not been written yet, and will be updated later... (Code modification: add search and paging functions)

Summary of basic knowledge:
Article Publishing System
1.articlePublish.html publish article page, submit to articlePublishDo.php page, execute writing to database
2.articleList.php article list page
3. Click Edit, modify the article and submit it to the aiticleEdit.php form page (echo)
4. Click the Modify Article button to submit to articleUpdate.php
I hope this article will be helpful to everyone’s PHP programming design.
