What is the page method of thinkphp?

The page method is one of the coherent operation methods of the model. It is a humanized operation method that was completely born for paging query.

Usage

We have already learned about the use of the limit method for paging queries, and the page method is a more humane method for paging queries. For example, taking article list paging as an example, if we use the limit method, we need to query the first and second pages (assuming we output 10 pieces of data per page). The writing is as follows:

$Article = M('Article');
$Article->limit('0,10')->select(); // 查询第一页数据
$Article->limit('10,10')->select(); // 查询第二页数据

Although using the extension class The paging class Page in the library can automatically calculate the limit parameter of each page, but it is more laborious to write it yourself. It is much simpler if you use the page method to write it, for example:

$Article = M('Article');
$Article->page('1,10')->select(); // 查询第一页数据
$Article->page('2,10')->select(); // 查询第二页数据

The obvious thing is , using the page method you do not need to calculate the starting position of each paged data, the page method will automatically calculate it internally.

After version 3.1, the page method also supports the writing of two parameters, for example:

$Article->page(1,10)->select();

and

$Article->page('1,10')->select();

are equivalent.

The page method can also be used in conjunction with the limit method, for example:

$Article->limit(25)->page(3)->select();

When the page method only has one value passed in, it indicates which page, and the limit method is used to set each page. The displayed quantity, that is to say, the above writing method is equivalent to:

$Article->page('3,25')->select();
