1、函数：
function showpage($page,$pagelistnum,$total,$style=1,$url='')
{
global $pagelist,$showpage,$_SERVER;
$page==''?$page=1:'';//如果page为空则为1，否则为空
$pagelist = ($page-1)*$pagelistnum;
$total % $pagelistnum==0?$totalpage = $total / $pagelistnumtotalpage = floor($total / $pagelistnum)+1;
$page>1?$uppage = $page-1uppage = 1;
$page>=$totalpage?$nextpage = $totalpagenextpage = $page+1;
$tabletr="<table width='100%' border='0' cellspacing='0' cellpadding='0'><tr><td height=20>";
$tabletd="</td></tr></table>";
$nav="  ";
$uppage=$page-1; //上一页
$dmpage=$page+1; //下一页
//如果$url使用默认，即空值，则赋值为本页URL：
if(!$url){ $url=$_SERVER["REQUEST_URI"];}
//URL分析：
$thispage =(stristr($url,'?page')!=false)?'?page':'&page';
$url=str_replace($thispage."=".$page,'',$url);
//Url里有"?"就加"&"没有就加"?"
if(stristr($url,'?')!=false){
$url.="&page";
}else {
$url.="?page";
}
switch($style) {
case '1':
//9首页 7前页 后页8 尾页:
$nav .=" 总计<B>$total</B>条记录. 当前第<B>$page</B>页，共<strong>$totalpage</strong>页. ";
if ($page > 1) {
$nav .= '<a href="'.$url.'=1"><font face=webdings>9</font>首页</a> ';
$nav .= '<a href="'.$url.'='.$uppage .'"><font face=webdings>7</font>前页</a> ';
}else {
$nav .= '<span><font face=webdings>9</font>首页</span> ';
$nav .= '<span><font face=webdings>7</font>前页</span> ';
}
if ($page < $totalpage) {
$nav .= '<a href="'.$url.'='.$dmpage.'">后页<font face=webdings>8</font></a> ';
$nav .= '<a href="'.$url.'='.$totalpage.'">尾页<font face=webdings>:</font></a>';
}else {
$nav .= '<span>后页<font face=webdings>8</font></span> ';
$nav .= '<span>尾页<font face=webdings>:</font></span>';
}
//下拉跳转列表，循环列出所有页码：
$nav .="　转到第 <select name='topage' size='1' onchange='window.location="$url="+this.value'>n";
for($i=1;$i<=$totalpage;$i++){
if($i==$page) $nav.="<option value='$i' selected>$i</option>n";
else $nav.="<option value='$i'>$i</option>n";
}
$nav.="</select> 页";
break;
case '2'://分页
$nav .="<table width="300" border="0" cellspacing="0" cellpadding="0">
<tr>
<td height="35" width=150>Total<B>$total</B>.Now<B>$page/$totalpage</b>age</td>
<td> </td>";
if ($page > 1) {
$nav .= '<td width="20"><a href="'.$url.'='.$uppage .'">First</a></td> ';
}else {
$nav .= '<td width="20"></td>';
}
$mid = ceil(($pagelistnum+1)/2);
if($page<=$mid ) {
$begin = 1;
}else if($page > $totalpage-$mid) {
$begin = $totalpage-$pagelistnum+1;
}else {
$begin = $page-$mid+1;
}
if($begin<0) $begin = 1;
$end = ($begin+$pagelistnum>$totalpage)?$totalpage+1begin+$pagelistnum;
$nav .="<td width="50" align="left">";
for($i=$begin; $i<$end; $i++) {
$nav .=($page!=$i)?" <a href='$url=$i' title='第{$i}页'>$i</a> ":" <b>$i</b>";
}
$nav .="</td>";
if ($page < $totalpage) {
$nav .= '<td width="50"><a href="'.$url.'='.$dmpage.'" class="page_linked">Last</a></td>';
}else {
$nav .= '';
}
$nav .='</tr></table>';
break;
}
$showpage=$tabletr.$nav.$tabletd;
return $showpage;
}

2、下来我们看如何调用
<?php
define('IN_ECS', true);
require(dirname(__FILE__) . '/includes/init.php');
include('common.php');
$page = !empty($_REQUEST['page']) ? intval($_REQUEST['page']) : 1;
/* 获得文章总数 */
$size   = 3;
$count  = get_article_count($cat_id);
$pages  = ($count > 0) ? ceil($count / $size) : 1;
if ($page > $pages)
{
$page = $pages;
}
$smarty->assign('pages_show',showpage($page,$size,$count,2,''));
$smarty->assign('articles_list',get_cat_articles($cat_id,$page,$size));//这是ec的一个获取文章的函数 在includes/lib_articles.php里。我们不用管。
$smarty->display("blog.dwt");
