Pagination of php Arrays

We recommend that you do not use php paging because the data is complete. You can use js Paging for the purpose of optimizing the display effect. This is not recommended because page Jump requires a long wait for visitors.

Usually, the database content is displayed on pages. For example, you need to display 100 entries, but only 10 entries are displayed at a time. One is faster display, and the other is mainly because the pressure on the database is reduced.

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