PHP 分页类叫 page.class.php
1 <?php 2 class pageTest 3 { 4 public $first_row; //起始行数 5 6 public $list_rows; //列表每页显示行数 7 8 public $total_pages; //总页数 9 10 public $total_rows; //总行数 11 12 public $now_page; //当前页数 13 14 public $method = 'defalut'; //处理情况 Ajax分页 Html分页(静态化时) 普通get方式 15 16 public $parameter = ''; 17 18 public $page_name; //分页参数的名称 19 20 //public $ajax_func_name; 21 22 public $plus = 3; //分页偏移量 23 24 public $url; 25 26 /** 27 * 构造函数 28 * @param unknown_type $data 29 */ 30 31 public function __construct($data = array()){ 32 33 $this->total_rows = $data['total_rows']; //总行数 34 35 $this->list_rows = !empty($data['list_rows']) && $data['list_rows'] <= 100 ? $data['list_rows'] : 15; 36 //每页显示行数 默认为15行 37 $this->total_pages = ceil($this->total_rows / $this->list_rows); 38 //总页数 39 $this->parameter = !empty($data['parameter']) ? $data['parameter'] : ''; //传递过来的参数 40 41 $this->page_name = !empty($data['page_name']) ? $data['page_name'] : 'p'; //传递参数的命名 42 43 $this->method = !empty($data['method']) ? $data['method'] : ''; 44 45 //当前页面 46 if(!empty($data['now_page'])){ 47 48 $this->now_page = intval($data['now_page']); 49 50 }else{ 51 52 $this->now_page = !empty($_GET[$this->page_name]) ? $_GET[$this->page_name] : 1; 53 54 } 55 56 $this->now_page = $this->now_page <= 0 ? 1 : $this->now_page; 57 58 if(!empty($this->total_pages) && ($this->now_page > $this->total_pages)){ 59 60 $this->now_page = $this->total_pages; 61 62 } 63 64 $this->first_row = $this->list_rows * ($this->now_page-1); 65 66 } 67 /* 测试功能的函数*/ 68 public function aa(){ 69 70 echo $_GET[$this->page_name]; 71 72 } 73 public function _get_link($page,$text){ 74 75 return '<a href="' . $this->_get_url($page) .

使用方法 我介绍的是在.php文件中的使用方法，因为本人本地 没有用html 与PHP 分离
代码是：
/*首先肯定是连接数据库，数据库类的代码我就不发了。*/ require_once("Page.class.php"); $tid='111'; $params = array( 'total_rows'=>10, #(必须) 'method' =>'', #(必须) 'parameter' =>'tid='.$tid, #(看情况，这个是传输的参数) 'now_page' =>$_GET['p'], #(必须) 'list_rows' =>2, #(可选) 默认为15 ); $page = new pageTest($params); $sql = "select title from dede_archives where 1 limit ".$page->first_row.",".$page->list_rows.""; $query = mysql_query($sql); $arr1 = array(); while($arr = mysql_fetch_array($query)){ echo "<br>".$arr[title]."<br>"; } ?> <div id="page"> <?php echo $page->show(1); echo "<br>"; ?></div> <style type="text/css"> #page{font:12px/16px arial} #page span{float:left;margin:0px 3px;} #page a{float:left;margin:0 3px;border:1px solid #ddd;padding:3px 7px; text-decoration:none;color:#666} #page a.now_page,#page a:hover{color:#fff;background:#05c} </style> //style 的是分页样式 //PHP 部分是 使用方法 //html 部分是 显示时用到的DIV
