thinkphp 分页 原理

1.分页是指把数据按照一定的规则分成若干页进行显示,提高浏

览效率。

Pagination refers to the division of data into pages

according to certain rules to improve browsing efficiency.

2.常见的分页方式包括基于页数分页和基于游标分页两种。

Common pagination methods include page-based pagination

and cursor-based pagination.

3.基于页数分页是指通过指定页码来获取数据,常见于传统的网

页浏览。

Page-based pagination refers to obtaining data by

specifying the page number, commonly used in traditional web

browsing.

4.基于游标分页是指通过游标标识来获取数据,常见于大数据量

的分页查询。

Cursor-based pagination refers to obtaining data by using

a cursor identifier, commonly used in pagination queries with

large amounts of data.

5.分页的实现原理通常涉及到计算总数据量、总页数,以及当前

页码等信息。

The implementation principle of pagination usually

involves calculating the total data amount, total pages, and

the current page number.

6.在数据库中,分页还需要考虑如何优化查询性能,避免数据过

多导致性能下降。

In a database, pagination also needs to consider how to

optimize query performance to avoid performance degradation

caused by excessive data.

7.在ThinkPHP中,可以使用paginate方法来实现分页功能,简

单方便。
