【急】php分页求一个php分页类，要有详细的使用例子。

//分页
function trans_pages($js_func_name,$js_parameters=0,$total,$pagesize=10,$nowpage=1){
if($nowpage<1){$rowpage=1;}
if($total%$pagesize){
$totalpage=intval($total/$pagesize)+1;
}else{
$totalpage=intval($total/$pagesize);
}
if($nowpage<$totalpage && $totalpage!=1){
$pageup=$nowpage-1;
$pagedown=$nowpage+1;
$pageup_string="上一页";
$pagedown_string="下一页";
}elseif($totalpage<=1){
$pageup=1;
$pagedown=1;
$pageup_string="上一页";
$pagedown_string="下一页";
}elseif($nowpage>=$totalpage){
$nowpage=$totalpage;
$pageup=$nowpage-1;
$pagedown=$totalpage;
$pageup_string="上一页";
$pagedown_string="下一页";
}
if($pageup<1){
$pageup=1;
$pageup_string="上一页";
} $array=array("up"=>$pageup,"down"=>$pagedown,"upstring"=>$pageup_string,"downstring"=>$pagedown_string);
return $array;
}
给你个精简过的分页trans_pages($js_func_name,$total,$nowpage=1,$js_parameters=0,$pagesize=10)
参数1：js函数名也是分页调用的js函数
参数2: ...
参数3：js参数
..........

去下载discuz论坛，然后看它里面的分页代码

下面是个分页类，你看懂了，样式可以自己改一下：

从网上下载adodb，里面有很好的分页，还有到处为CSV文件功能，直接调用的，下面是我调用写的分页，就一两行代码<?php
include("adodb/adodb.inc.php");//必须导入的
include("adodb/toexport.inc.php");//分页用的
include("adodb/adodb-pager.inc.php");$host="localhost";
$dbname="root";
$dbpass="root";
$db="*****";$conn=ADONewConnection("mysql");//选择需要链接的数据库种类，这里是链接mysql数据库$conn->Connect($host,$dbname,$dbpass,$db);//链接$conn->Execute("set names gb2312");
$sql="select * from *****";$rs=$conn->Execute($sql);$pager=new ADODB_Pager($conn,$sql);
pager->Render($rows_per_page=3);//每页显示3条记录
?>
