最简单的分页方法

<?php
$conn = mysql_connect('localhost','root','mysql');
$db = mysql_select_db("wiki");
$q = mysql_query("select * from wiki_doc");

$num = mysql_num_rows($q);
$perpage = 5;
$totalpage = @ceil($num/$perpage);
$page =$_GET['page'];

if(!isset($page)){
$page = 1;

}

//$start = ($page-1)*$perpage;
$start = ($page-1)*$perpage;
$qq=mysql_query("select * from wiki_doc limit $start,$perpage");
$info = array();
while($result=mysql_fetch_array($qq)){
$info[] = $result;
}

echo "<table>";
foreach($info as $key){
echo "<tr><td>$key[did]</td><td> </td><td>$key[title]</td></tr>";
}
echo "</table>";
if($page!=1){?>
<a href="page2.php?page=<?php echo $page-1; ?>">Prev</a>
<?php
}
for($i=1;$i<=$totalpage;$i++){
?>
<a href="page2.php?page=<?php echo $i; ?>"><?php echo $i; ?></a>
<?php

}
if($page<$totalpage){?>
<a href="page2.php?page=<?php echo $page+1; ?>">Next</a>
<?php
}?>
