PHP paging implementation (with renderings)_PHP tutorial

First, a paging class, as shown below (extracted from the Internet) can be copied and used directly

<?php
/*
 * Created on 2013-12-3

 */
class Pagination {
	private $each_disNums; //每页显示的条目数
	private $nums; //总条目数
	private $current_page; //当前被选中的页
	private $sub_pages; //每次显示的页数
	private $pageNums; //总页数
	private $page_array = array (); //用来构造分页的数组
	private $subPage_link; //每个分页的链接
	private $subPage_type; //显示分页的类型
	/*
	__construct是SubPages的构造函数，用来在创建类的时候自动运行.
	@$each_disNums 每页显示的条目数
	@nums 总条目数
	@current_num 当前被选中的页
	@sub_pages 每次显示的页数
	@subPage_link 每个分页的链接
	@subPage_type 显示分页的类型

	当@subPage_type=1的时候为普通分页模式
	example： 共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页]
	当@subPage_type=2的时候为经典分页样式
	example： 当前第1/453页 [首页] [上页] 1 2 3 4 5 6 7 8 9 10 [下页] [尾页]

in the php file that needs paging

include_once ("Pagination.php");
//每页显示的条数
$pageSize = 10;
//总条目数
$pageTotal = $db->get_var("select count(*) from tb");
//每次显示的页数
$sub_pages = 10;
//得到当前是第几页
if (is_array($_GET) && count($_GET) > 0) {
	if (isset ($_GET["p"])) { //是否存在"id"的参数
		$pageCurrent = $_GET["p"];
	}
} else {
	$pageCurrent = 1;
}
$goodses = $db->get_results("SELECT g.id,* FROM tb as g INNER JOIN (select id from tb  order by updatetime desc limit " . ($pageCurrent -1) * $pageSize . ",10 )as g1 ON g.id=g1.id");

Display pagination data

<?php $subPages = new Pagination($pageSize, $pageTotal, $pageCurrent, $sub_pages, "index.php?p=", 2);?>
