经典php分页代码,支持数字偏移

这款php分页代码是一款完整的php mysql css的经典分页功能,很适合于大分类有像phpwindow dz等论坛效果.

CSS样式代码如下:

<style type= "text/css" >  </style>
PHP实例效果代码如下:

<?php mysql_connect( 'localhost' , 'root' , '' ); mysql_select_db( 'news' ); mysql_query( 'set names gbk' ); $sql = mysql_query( "select * from `v_char`" ); $num = mysql_num_rows( $sql ); include 'page.class.php' ; /*参数说明： *getpages($pagesize,$pagenum,$page,$init,$page_len); *$pagesize 每页记录 *$pagenum 总记录数 *$page $_get[page] *$init 数字分页最小数，默认为1，一般不用更改。 *$page_len 数字分页的数量。 */ $model = new getpages(10, $num , $_get [ 'page' ]); $sql = "select * from `v_char` limit $model->offset,$model->pagesize" ; $res = mysql_query( $sql ); while ( $row = mysql_fetch_assoc( $res )) { echo $row [ 'id' ] . " - " . $row [ 'name' ] . '<br>' ; } //输出分页信息 echo $model ->getpage(); ?> page. class .php <?php /* * author：陈凯 * data：2010-09-14 */ class getpages { public $pagesize ; //每页记录 public $offset ; //起始记录数 public $pagenum ; //总记录 public $page ; //当前页码 public $init ; //数字分页最左边数字 public $page_len ; //数字分页最右边数字 public $pages ; //总页数 //初始化赋值。 function __construct( $pagesize , $pagenum , $page , $init =1, $page_len =7) { $this ->pagesize = $pagesize ; //每页记录 $this ->pagenum = $pagenum ; //总记录 $this ->page = $page ; $this ->pages = ceil ( $this ->pagenum/ $this ->pagesize); //总页数 if ( empty empty ( $this ->page) || $this ->page <1 || $this ->page > $this ->pages) $this ->page=1; $this ->init = $init ; //数字分页左 $this ->page_len = $page_len ; //数字分页右 $this ->offset = ( $this ->page-1)* $this ->pagesize; } //输出分页 function getpage() { $this ->prepg = $this ->page-1; //上一页 $this ->nextpg= ( $this ->page == $this ->pages) ? 0 : $this ->page+1; //下一页 // if($this->pages == 1) return false; //如果只有一页跳出 $pagenav = "<span class='divs'>共 " . $this ->pages.

"</a>" ; } else { $pagenav .= "<a href='" . $this ->get_url(). "=" . $i . "' class='div'>" . $i . "</a>" ; } } return $pagenav ; } //获取url地址 function get_url() { $url = $_server [ 'request_uri' ]; $parse_url = parse_url ( $url ); $query_url = $parse_url [ 'query' ]; //取出url上的参数 if ( $query_url ) { //将&page 替换为空 $query_url = ereg_replace ( "(^|&)page=$this->page" , "" , $query_url ); $url = str_replace ( $parse_url [ 'query' ], $query_url , $url ); if ( $query_url ) $url .= '&page' ; else $url .= 'page' ; } else { $url .= '?page' ; } return $url ; } } ?>
