高分求PHP~~翻页代码~~要求每页显示5-10条数据库中的数据~~越简单越好

高分求PHP~~翻页代码~~要求每页显示5-10条数据库中的数据~~越简单越好

一、分页类的内容


function totalNum($sql_t)
{
$res_totalNum = mysql_query($sql_t);
if($row_totalNum = mysql_fetch_row($res_totalNum))
{
$totalNum = $row_totalNum[0];
return $totalNum;
}
}


function curPage()
{
if(isset($_REQUEST["curpage"]))
{
$curPage = $_REQUEST["curpage"];
}
else
{
$curPage = 1;
}
return $curPage;
}


function page($pageSize,$sql_t)
{
$totalNum = totalNum($sql_t); //总页数

if($totalNum%$pageSize == 0)
{
$pageNum = $totalNum/$pageSize;
}
else
{
$pageNum = (int)($totalNum/$pageSize) + 1;
}
return $pageNum;
}

function record($curPage,$pageSize,$sql_g)
{
$sql_getRecord = $sql_g." limit ".($curPage-1)*$pageSize.",".$pageSize."";
$res_getRecord= mysql_query($sql_getRecord);
return $res_getRecord;
}

function pageDiv($pageSize,$sql_t,$pageName)
{
$curPage = curPage();
$pageNum = page($pageSize,$sql_t); //获得总分页数
if($curPage != 1)
{
$p1 = $curPage - 1;
echo "上一页";
echo "  ";
echo "".$p1."";
echo "  ";
}
else
{
echo "当前是第一页";
echo "  ";
}

echo "".$curPage."";


if($curPage != $pageNum && $pageNum >0)
{
$p2 = $curPage + 1;
echo "  ";
echo "".$p2."";
echo "  ";

echo "下一页";
}
else
{
echo "  ";
echo "当前是最后一页";
}

}

?>
二、调用的页面










include "getdb.php";
$d3b = new DB;
$d3b->init($host,$user,$pwd,$db);
$d3b->selDB();

include "divpage.php";
$curPage = curPage();
$res_getRecord = record($curPage,5,"select * from user");

while($row_getRecord = mysql_fetch_row($res_getRecord))
{
echo $row_getRecord[1]."
";
}

pageDiv(5,"select count(*) from user","test.php?");
?>
