PHP paging class code, supports pseudo-static PHP paging class

class Page{

 protected $each_disNums;//The number of entries displayed on each page
 protected $nums;//The total number of entries
 protected $current_page;//The currently selected page
 protected $sub_pages;//The number of pages displayed each time
 protected $pageNums;//Total number of pages
 protected $page_array = array();//Array used to construct paging
 protected $subPage_link;//Each paging Link
 protected $subPage_type;//Display the type of paging
 protected $houz;//Suffix
/*
__construct is the constructor of SubPages, which is used to run automatically when creating a class.
@$each_disNums Entries displayed on each page Number
@nums The total number of entries
@current_num The currently selected page
@sub_pagesThe number of pages displayed each time
@subPage_linkThe link of each page
@subPage_type displays the type of paging

When @subPage_type=1, it is normal Pagination mode
 example: 4523 records in total, 10 records displayed on each page, current page 1/453 [Home] [Previous page] [Next page] [Last page]
 When @subPage_type=2, it is the classic paging style
 example: Current page 1/453 [Home page] [Previous page] 1 2 3 4 5 6 7 8 9 10 [Next page] [Last page]

Usage: Instantiate this page class, $list = new Page (how many pieces of data per page, total amount of data, current page, array used to construct paging, link for each paging, type of paging displayed, suffix); For example $list = new Page(10,1000,1,10,’/zjjz/’,2,’.html’); echo $page = $list->subPageCss2(); It will display: Current page 1/100 [Home page] [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... . The links of each page can be combined according to direct needs to achieve pseudo-static.

And ajax paging is

$list = new Page($pagesize,$areaAllNumber,$current_page,10,”,3); $url = $val1.’,’.$val2;//This is the value to be passed in the js function you want to trigger, $page = $list->subPageCss3(‘checkProducts’,$url);//The first parameter is the js function to be triggered. Thus achieving the effect of ajax paging.

There is also a subPageCss1 with a total of 4523 records, 10 records are displayed on each page, and the current page is 1/453 [Homepage] [Previous Page] [Next Page] [Last Page] This simple style also supports pseudo-static.
