首先一个分页类，如下（摘自网络）可拷贝直接使用

<?php /* * Created on 2013-12-3 * 分页类 * To change the template for this generated file go to * Window - Preferences - PHPeclipse - PHP - Code Templates */ 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] */ function __construct($each_disNums, $nums, $current_page, $sub_pages, $subPage_link, $subPage_type) { $this->each_disNums = intval($each_disNums); $this->nums = intval($nums); if (!$current_page) { $this->current_page = 1; } else { $this->current_page = intval($current_page); } $this->sub_pages = intval($sub_pages); $this->pageNums = ceil($nums / $each_disNums); $this->subPage_link = $subPage_link; $this->show_SubPages($subPage_type); //echo $this->pageNums."--".$this->sub_pages; } /* __destruct析构函数，当类不在使用的时候调用，该函数用来释放资源。 */ function __destruct() { unset ($each_disNums); unset ($nums); unset ($current_page); unset ($sub_pages); unset ($pageNums); unset ($page_array); unset ($subPage_link); unset ($subPage_type); } /* show_SubPages函数用在构造函数里面。而且用来判断显示什么样子的分页 */ function show_SubPages($subPage_type) { if ($subPage_type == 1) { $this->subPageCss1(); } elseif ($subPage_type == 2) { $this->subPageCss2(); } } /* 用来给建立分页的数组初始化的函数。 */ function initArray() { for ($i = 0; $i < $this->sub_pages; $i++) { $this->page_array[$i] = $i; } return $this->page_array; } /* construct_num_Page该函数使用来构造显示的条目即使：[1][2][3][4][5][6][7][8][9][10] */ function construct_num_Page() { if ($this->pageNums < $this->sub_pages) { $current_array = array (); for ($i = 0; $i < $this->pageNums; $i++) { $current_array[$i] = $i +1; } } else { $current_array = $this->initArray(); if ($this->current_page <= 3) { for ($i = 0; $i < count($current_array); $i++) { $current_array[$i] = $i +1; } } elseif ($this->current_page <= $this->pageNums && $this->current_page > $this->pageNums - $this->sub_pages + 1) { for ($i = 0; $i < count($current_array); $i++) { $current_array[$i] = ($this->pageNums) - ($this->sub_pages) + 1 + $i; } } else { for ($i = 0; $i < count($current_array); $i++) { $current_array[$i] = $this->current_page - 2 + $i; } } } return $current_array; } /* 构造普通模式的分页共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页] */ function subPageCss1() { $subPageCss1Str = ""; $subPageCss1Str .= "共" . $this->nums .

($this->current_page - 1); $subPageCss1Str .= "[<a href='$firstPageUrl'>首页</a>] "; $subPageCss1Str .= "[<a href='$prewPageUrl'>上一页</a>] "; } else { $subPageCss1Str .= "[首页] "; $subPageCss1Str .= "[上一页] "; } if ($this->current_page < $this->pageNums) { $lastPageUrl = $this->subPage_link . $this->pageNums; $nextPageUrl = $this->subPage_link . ($this->current_page + 1); $subPageCss1Str .= " [<a href='$nextPageUrl'>下一页</a>] "; $subPageCss1Str .= "[<a href='$lastPageUrl'>尾页</a>] "; } else { $subPageCss1Str .= "[下一页] "; $subPageCss1Str .= "[尾页] "; } echo $subPageCss1Str; } /* 构造经典模式的分页当前第1/453页 [首页] [上页] 1 2 3 4 5 6 7 8 9 10 [下页] [尾页] */ function subPageCss2() { $subPageCss2Str = ""; $subPageCss2Str .= "当前第" . $this->current_page . "/" . $this->pageNums . "页 "; if ($this->current_page > 1) { $firstPageUrl = $this->subPage_link . "1"; $prewPageUrl = $this->subPage_link . ($this->current_page - 1); $subPageCss2Str .= " <a href='$firstPageUrl'>首页</a> "; $subPageCss2Str .= " <a href='$prewPageUrl'>上一页</a> "; } else { $subPageCss2Str .= " 首页 "; $subPageCss2Str .= " 上一页 "; } $a = $this->construct_num_Page(); for ($i = 0; $i < count($a); $i++) { $s = $a[$i]; if ($s == $this->current_page) { $subPageCss2Str .= " <span style='color:red;font-weight:bold;'>" . $s . " "; } else { $url = $this->subPage_link . $s; $subPageCss2Str .= " <a href='$url'>" . $s . "</a> "; } } if ($this->current_page < $this->pageNums) { $lastPageUrl = $this->subPage_link . $this->pageNums; $nextPageUrl = $this->subPage_link . ($this->current_page + 1); $subPageCss2Str .= " <a href='$nextPageUrl'>下一页</a> "; $subPageCss2Str .= " <a href='$lastPageUrl'>尾页</a> "; } else { $subPageCss2Str .= " 下一页 "; $subPageCss2Str .= " 尾页 "; } echo $subPageCss2Str; } } ?>

在需要分页的php文件中

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");

显示分页数据

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