php最简单php分页代码

<?php
//初始参数设置
$pagesize=5 ;  //分页大小
$pagenum=1 ;  //默认为第一页

//第一步：获取当前是第几页
if($_GET){
 if($_GET['pagenum']){  
  $pagenum=$_GET['pagenum'];
 }
}
//第二步：获取当前分页的内容列表
$sql="Select * From message limit ".($pagenum-1)*$pagesize.",$pagesize ";
$result=mysql_query($sql);
while(($row=mysql_fetch_array($result))==true){
 echo '<hr>'.$row["title"].'</hr>';
}
//第三步：获取记录数
$sql="Select id From message";
$result=mysql_query($sql);
$rownum=mysql_num_rows($result);
//第四步：记算分页数
if(($rownum%$pagesize)==0){
 $pagecount=$rownum/$pagesize;
}else{
 $pagecount=(int)($rownum/$pagesize);
}
//第五步：得到分页链接
http://pic1.phprm.com/2011/07/14/$url.jpg=$_SERVER["REQUEST_URI"];
$url=parse_url($url);
$url=$url["path"];
//第六步：输出分页链接
if($pagenum==1){ 
 echo "[第一页]  [上一页]";
}else{
 echo "[<a href="$url?pagenum=1">第一页</a>]  [<a href="$url?pagenum=".($pagenum-1)."">上一页</a>]";
}

if($pagecount==$pagenum){
 echo "[下一页]  [最后一页]"; 
}else{
echo "[<a href="$url?pagenum=".($pagenum+1)."">下一页</a>]  [<a href="$url?pagenum=".($pagecount)."">最后一页</a>]";
}
