一个简单明了的目的是为了学习
<?
$per_page=10;
//put FROM and WHERE parts into separate variable
$from_where="FROM table WHERE filter=1";
//getting total number of records
$res=mysql_query("SELECT count(id) ".$from_where);
$row=mysql_fetch_row($res);
$total_rows=$row[0];
//Process GET variables to get $start value for LIMIT
if (isset($_GET['page'])) $CUR_PAGE=($_GET['page']); else $CUR_PAGE=1;
$start=abs(($CUR_PAGE-1)*$per_page);
//getting records from database into array
$query="SELECT * $from_where ORDER BY date DESC LIMIT $start,$per_page";
$res=mysql_query($query);
while ($row=mysql_fetch_array($res)) $DATA[++$start]=$row;
//Getting page URL without query string
$uri=strtok($_SERVER['REQUEST_URI'],"?")."?";
//create a new query string without a page variable
if (isset($_GET['page'])) unset($_GET['page']);
if (count($_GET)) {
foreach ($_GET as $k => $v) {
if ($k != "page") $uri.=urlencode($k)."=".urlencode($v)."&";
}
}
//getting total number of pages and filling an array with links
$num_pages=ceil($total_rows/$per_page);
for($i=1;$i<=$num_pages;$i++) $PAGES[$i]=$uri.'page='.$i;
//and here goes a simple template
?>
Total records: <b><?=$total_rows?></b><br><br>
<? foreach ($DATA as $i => $row): ?>
<?=$i?>. <a href="?id=<?=$row['id']?>"><?=$row['title']?></a><br>
<? endforeach ?>
<br>
Pages:
<? foreach ($PAGES as $i => $link): ?>
<? if ($i == $CUR_PAGE): ?>
<b><?=$i?></b>
<? else: ?>
<a href="<?=$link?>"><?=$i?></a>
<? endif ?>
<? endforeach ?>

秘密在于SQL的SELECT ... LIMIT x OFFSET y clauses。
答案 3 :(得分：0)
这不难做到。这是一个快速和快速的配方;简单的系统：
执行SELECT查询，添加子句LIMIT PERPAGE *（PAGENUM-1），PERPAGE请注意，all in caps变量可以是脚本的GET参数。
如果没有LIMIT子句，则查找SELECT查询的结果总数（有方法可以执行此操作，例如，MySQL的SELECT“SQL_CALC_FOUND_ROWS * FROM ...”，它将被集成进入＃1。）调用此N
向用户显示数据，以及“显示项目PERPAGE *（PAGENUM-1）+1到PERPAGE * PAGE N”
我会发布一个示例，但我的查询和数据库句柄在我的代码中的其他地方处理。

虽然指南是丹麦语，但我相信您可以轻松理解并使用本网站的摘要类：http://www.jensgram.dk/web/e-artikler/1265（靠近底部）。
您需要做的就是实施renderItem()方法，然后关闭：
class PaginatedGuestbook extends Paginator {
protected function renderItem(&$row) {
$o = "\Post from " . $row['name'] . "<br />\n"
. "Header: <b>" . $row['header'] . "</b><br />\n"
. "Text: " . $row['body'] . "<br />\n";
// You can do whatever you want with the $row array
return $o;
}
}
$gb = new PaginatedGuestbook(
'guestbook_table', // Table(s)
'tstamp, name, header, body', // Fields to populate in renderItem's $row
'hidden=0 AND deleted=0', // Condition
'tstamp DESC', // Ordering
5 // Items per page
);
print $gb->renderItems();
print "<br />\n\n";
print $gb->renderNavigation('paginated.php');
此外，您可以自定义链接等。

答案 6 :(得分：-1)
我有一个很好的分页例子：
<?php
/*
Place code to connect to your DB here.
*/
include('config.php'); // include your code to connect to DB.
$tbl_name=""; //your table name
// How many adjacent pages should be shown on each side?
$adjacents = 3;
/*
First get total number of rows in data table.
If you have a WHERE clause in your query, make sure you mirror it here.
*/
$query = "SELECT COUNT(*) as num FROM $tbl_name";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];
/* Setup vars for query. */
$targetpage = "filename.php"; //your file name (the name of this file)
$limit = 2; //how many items to show per page
$page = $_GET['page'];
if($page)
$start = ($page - 1) * $limit; //first item to display on this page
else
$start = 0; //if no page var is given, set start to 0
/* Get data. */
$sql = "SELECT column_name FROM $tbl_name LIMIT $start, $limit";
$result = mysql_query($sql);
/* Setup page vars for display. */
if ($page == 0) $page = 1; //if no page var is given, default to 1.
$prev = $page - 1; //previous page is page - 1
$next = $page + 1; //next page is page + 1
$lastpage = ceil($total_pages/$limit); //lastpage is = total pages / items per page, rounded up.
$lpm1 = $lastpage - 1; //last page minus 1
/*
Now we apply our rules and draw the pagination object.
We're actually saving the code to a variable in case we want to draw it more than once.
*/
$pagination = "";
if($lastpage > 1)
{
$pagination .= "<div class=\"pagination\">";
//previous button
if ($page > 1)
$pagination.= "<a href=\"$targetpage?page=$prev\">« previous</a>";
else
$pagination.= "<span class=\"disabled\">« previous</span>";
//pages
if ($lastpage < 7 + ($adjacents * 2)) //not enough pages to bother breaking it up
{
for ($counter = 1; $counter <= $lastpage; $counter++)
{
if ($counter == $page)
$pagination.= "<span class=\"current\">$counter</span>";
else
$pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";
}
}
elseif($lastpage > 5 + ($adjacents * 2)) //enough pages to hide some
{
//close to beginning; only hide later pages
if($page < 1 + ($adjacents * 2))

$pagination.= "<a href=\"$targetpage?page=$lastpage\">$lastpage</a>";
}
//in middle; hide some front and some back
elseif($lastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2))
{
$pagination.= "<a href=\"$targetpage?page=1\">1</a>";
$pagination.= "<a href=\"$targetpage?page=2\">2</a>";
$pagination.= "...";
