PHP分页函数代码（简单实用型）

准备数据：

新建一个数据库 test
执行下面的语句（新建一个表 test ：id、sex、name 三个字段）

CREATE TABLE `test` (
`id` INT( 4 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`sex` INT( 1 ) NOT NULL ,
`name` VARCHAR( 20 ) NOT NULL ) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_bin;

添加数据到 test 表，比如：
1 1 小强
2 0 小红
3 0 小丽
4 1 小兵
5 1 张三
6 0 李四
7 0 吴欣

写PHP语句（index.php）：
代码如下:

<?php 
// Page分页函数 
$page = $_GET["page"]; 
function Page($rows,$page_size){ 
global $page,$select_from,$select_limit,$pagenav; 
$page_count = ceil($rows/$page_size); 
if($page <= 1 || $page == '') $page = 1; 
if($page >= $page_count) $page = $page_count; 
$select_limit = $page_size; 
$select_from = ($page - 1) * $page_size.','; 
$pre_page = ($page == 1)? 1 : $page - 1; 
$next_page= ($page == $page_count)? $page_count : $page + 1 ; 
$pagenav .= "第 $page/$page_count 页 共 $rows 条记录 "; 
$pagenav .= "<a href='?page=1'>首页</a> "; 
$pagenav .= "<a href='?page=$pre_page'>前一页</a> "; 
$pagenav .= "<a href='?page=$next_page'>后一页</a> "; 
$pagenav .= "<a href='?page=$page_count'>末页</a>"; 
$pagenav.="　跳到<select name='topage' size='1' onchange='window.location=\"?page=\"+this.value'>\n"; 
for($i=1;$i<=$page_count;$i++){ 
if($i==$page) $pagenav.="<option value='$i' selected>$i</option>\n"; 
else $pagenav.="<option value='$i'>$i</option>\n"; 
} 
} // Page分页函数 
// 使用示例 
if (!$conn= mysql_connect("localhost", "root" ,"root")) die('数据库选择失败！'); 
if (!mysql_select_db("test", $conn)) die('数据库选择失败！'); 
mysql_query('set names GBK'); 
// 用Page函数计算出 $select_from 从哪条记录开始检索、$pagenav 

输出分页导航
$rows = mysql_num_rows(mysql_query("select * from test"));
Page($rows,2);
$sql = "select * from test limit $select_from $select_limit";
$rst = mysql_query($sql);
while ($row = mysql_fetch_array($rst)){
echo "$row[id] - $row[sex] - $row[name] <hr />";
}
echo $pagenav;
?>

浏览 index.php 页面，如图：

该说byebye了，确实好用！

PHP简单分页函数
写了一个php简单的分页函数，数据库调用也写到里面了 ，用的人可以自行删减！
代码如下:

function getask(){ 
$sql = "select * from cms_ask where ansower <> ' ' "; 
//这里要改成方法 
$q_sq = mysql_query($sql); 
$count = mysql_num_rows($q_sq); 
$page_size = 8; 
$page_current = isset($GLOBALS['page']) ? intval($GLOBALS['page']) : 1; 
$page_count = ceil($count / $page_size); 
$page_start = $page_current - 4; 
$page_end = $page_current + 4; 
if ($page_current < 5) { 
$page_start = 1; 
$page_end = 5; 
} 
if ($page_current > $page_count - 4) { 
$page_start = $page_count - 8; 
$page_end = $page_count; 
} 
if ($page_start < 1) 
$page_start = 1; 
if ($page_end > $page_count) 
$page_end = $page_count; 
$pagebar = ""; 
$sql = "select * from cms_ask where ansower <> ' ' order by id desc limit " . (($page_current - 1) * $page_size) . "," . $page_size; 
$row=$this -> user -> getall("$sql"); 
foreach($row as $v){ 
echo '<dl><dt>问：'.$v["question"].'</dt><dd>答：'.$v["ansower"].date("Y-m-d H:i:s",$v["postTime"]).'</dd></dl>'; 

} 

$pagebar .= "<div class=\"page\">"; 
$pagebar .= "<ol>"; 
if ($page_current != 1) { 
$pagebar .= '<li><a href="javascript:get_comment(1)" class="sx">FIRST</a></li>'; 
} 
for ($i = $page_start; $i <= $page_end; $i++) { 
if ($i == $page_current) { 
$pagebar .= "<li><span class=\"sort\">" . $i . "</span></li>"; 
} else { 
$pagebar .= "<li><a href='javascript:get_comment(" . $i . ")'>" . $i . "</a></li>"; 
} 
} 

if ($page_current != $page_count) { 
$pagebar .= "<li><a href='javascript:get_comment(" . $page_count . ")' class='sx'>END</a></li>"; 
} 
$pagebar .= "</ol>"; 
$pagebar .= " </div>"; 
echo $pagebar; 
}
