In PHP, paging is a common technique used to divide large amounts of data into small pieces for display. Pagination not only improves web page loading speed, but also provides a better user experience. In PHP, the following attribute set is usually required to implement paging:

1. Current page number (current_page): Indicates which page is currently displayed. This attribute is determined based on the user's operation or request.

2. The number of data displayed on each page (page_size): Determine the number of data displayed on each page. This property can be adjusted according to actual needs to display a reasonable amount of data.

3. Total data quantity (total_count): Indicates the total amount of data in the entire data set. This property is obtained based on a database query or other methods.

4. Total number of pages (total_page): The total number of pages calculated based on the number of data displayed on each page and the total number of data.

5. Number of visible page numbers (visible_pages): Determine the number of page numbers displayed in paging navigation. For example, you can set up to display only 5 pages before and after, and the excess page numbers are indicated by ellipses.

6. Previous page (prev_page) and next page (next_page): represent the previous and next pages of the current page respectively. Users can switch pages by clicking on the previous and next page buttons.

7. Paging navigation links (page_links): Links displayed in the paging navigation bar. Click the link to switch to different pages.
