分页显示的代码:

<?php

}

while ($myrow = mysql_fetch_array($res));

}

?>

<?

echo "<div align='center'>共有".$pages."页(".$page."/".$pages.")<br>";

//显示分页数

for ($i=1;$i<$page;$i++)

echo "<a href='index.php?page=".$i."'>第".$i ."页</a> ";

echo "第".$page."页 ";

for ($i=$page+1;$i<=$pages;$i++)

echo "<a href='index.php?page=".$i."'>第".$i ."页</a> ";

echo "<br>";

//显示转到页数

echo "<form action='index.php' method='post'> ";

//计算首页、上一页、下一页、尾页的页数值

$first=1;

$prev=$page-1;

$next=$page+1;

$last=$pages;

if ($page>1)

{

echo "<a href='index.php?page=".$first."'>首页</a> ";

echo "<a href='index.php?page=".$prev."'>上一页</a> ";

}

if ($page<$pages)

{

echo "<a href='index.php?page=".$next."'>下一页</a> ";

echo "<a href='index.php?page=".$last."'>尾页</a> ";

}

echo "转到<input type=text name='ys' size='2' value=".$page.">页";

echo "<input type=submit name='Submit' value='Go'>";

echo "</form>";

echo "</div>";
