$pagesize = 2; //一页显示记录数

$con = odbc_connect("access_test","","",SQL_CUR_USE_ODBC) or die("无法连接ODBC数据源access_test"); //连接一个ODBC数据源
$sql = "select count(*) as total from test"; //取得记录总数SQL语句
$rst = odbc_exec($con,$sql) or die("$sql查询出错"); //执行取得记录总数SQL语句
$recordcount = odbc_result($rst,1); //取得记录总数,在这里也可以用$recordcount = odbc_result($rst,"total");
odbc_free_result($rst); //释放资源

$pagecount = bcdiv($recordcount+$pagesize-1,$pagesize,0); //算出总页数

if(!isset($page)) $page = 1; //如果没有指定显示页码,缺省为显示第一页
if($pageif($page>$pagecount) $page = $pagecount; //如果页码比总页数大,则显示最后一页

if($page>0){ //页码比0大,表示有数据
   echo '>> 分页 ';
   echo '首页 ';
