Usage: instantiate this page class, $ list = new Page (how many pieces of data per page, total amount of data, current Page, used to construct an array of pages, each page link, display the type and suffix of the Page. for example, $ list = new page (, '/zjjz/', '); echo $ Page = $ list-> subPageCss2 (); it will be displayed: the current page 1/100 [Homepage] [Previous Page] 1 2 3 4 5 6 7 8 9 10 [Next Page] [last Page] each connection is/zjjz/1.html, /zjjz/2.html ....... You can combine the links of each page as needed to achieve pseudo-static.

While ajax paging is

$ List = new Page ($ pagesize, $ areaAllNumber, $ current_page, 10, ", 3); $ url = $ val1 .','. $ val2; // The value to be passed in the js function to be triggered. $ page = $ list-> subPageCss3 ('checkproducts', $ url ); // The first parameter is the js function to be triggered. To achieve the ajax paging effect.

There is also a subPageCss1 that contains a total of 4523 records, each page shows 10, the current 1/453 page [Homepage] [Previous Page] [Next Page] [last Page] this simple style, it also supports pseudo-static.
