$phpfile = index.php;//页面文件名
$page= isset($_GET[page])?$_GET[page]:1;//默认页码
$db = mysql_connect(localhost,test,test);//链接数据库
mysql_select_db(test,$db);//选择数据库
$counts = mysql_num_rows(mysql_query(select `id` from `test`,$db));//获取需要的数据总条数
$sql=select `id`,`title` from `test`;//定义查询语句SQL
$getpageinfo = page($page,$counts,$phpfile);//调用函数,生成分页HTML 和 SQL LIMIT 子句
$sql.=$getpageinfo[sqllimit];//组合完整的SQL语句
$data = $row = array();//初始化数组
$result = mysql_query($sql,$db);//获取结果集
//将数据装入$data数组
while($row = mysql_fetch_array($result)){
$data[]=$row;
}
?>
echo $getpageinfo[pagecode];//显示分页的html代码
?>
