php array paging display problem

It is not recommended to use php paging because the data is complete. If you want to paginate for the purpose of optimizing the display effect, you can use js. Because page jumps require visitors to wait for a long time, this is not recommended.

Usual paging is to paginate the database content. For example, 100 items need to be displayed, but only 10 items are displayed at a time. One of the reasons is that the display is faster, and the other main reason is to reduce the pressure on the database side.

You can simply put them in multiple divs and control the display and hiding of the divs through the previous page and the next page.
