、<?PHP //1,将数据库的所有记录查询出来,然后再一页一页的显示 $link=mysql_connect('localhost','root','123') ; mysql_select_db('yanhua'); mysql_query("set names utf8"); //首先要=知道每页显示几条记录 pagesize //第几页 page //下一页要掠过之前的几个记录 offset /* 0 0 0 0 0 0 0 0 0 page offset pagesize 1 0 2 2 2 2 3 4 2 4 6 2 */ //我们还是通过传递page参数的形式来判断当前是第几页 //?page = 1 第一页 ?page=2 第二页 page=3 第三也 $pagesize = 2; $page = isset($_GET['page'])?$_GET['page']:1; //通过page 和 pagesize 求出offset $offset = $pagesize * ($page-1); include ("libs/Smarty.class.php"); $smarty = new Smarty(); $smarty->reInitSmarty("demo/templates","demo/templates_c","demo/config","demo/cache"); $array_new=array(); $sql = "select * from news limit $offset,$pagesize"; $res = mysql_query($sql); while($row = mysql_fetch_assoc($res)){ $array_new[]=$row; } //var_dump($array_new); $smarty->assign("array_new",$array_new); $smarty->display("news.tpl"); $sql = "select count(*) as total from news"; $result = mysql_query($sql); //总的记录数 $row = mysql_fetch_assoc($result); $total_rows = $row['total']; $total_page = ceil($total_rows/$pagesize); echo '<a href="new.php">首页</a>'; //第一页的时候没有上一页 if($page > 1){ echo '<a href="new.php?page='.($page-1).'">上一页</a>'; echo ' '; } //尾页的时候不显示下一页 if($page < $total_page){ echo '<a href="new.php?page='.($page+1).'">下一页</a>'; echo ' '; } echo '<a href="new.php?page='.$total_page.'">尾页</a>';
