PHP分頁函數(shù)代碼（簡單實(shí)用型）

PHP分頁函數(shù)代碼（簡單實(shí)用型），學(xué)習(xí)php分頁的朋友可以參考下。

準(zhǔn)備數(shù)據(jù)：

新建一個(gè)數(shù)據(jù)庫 test
執(zhí)行下面的語句（新建一個(gè)表 test ：id、sex、name 三個(gè)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;

添加數(shù)據(jù)到 test 表，比如：
1 1 小強(qiáng)
2 0 小紅
3 0 小麗
4 1 小兵
5 1 張三
6 0 李四
7 0 吳欣

寫PHP語句（index.php）：

復(fù)制代碼代碼如下:

 
<?php 
// Page分頁函數(shù) 
$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 頁&nbsp;共 $rows 條記錄&nbsp;"; 
$pagenav .= "<a href='?page=1'>首頁</a>&nbsp;"; 
$pagenav .= "<a href='?page=$pre_page'>前一頁</a>&nbsp;"; 
$pagenav .= "<a href='?page=$next_page'>后一頁</a>&nbsp;"; 
$pagenav .= "<a href='?page=$page_count'>末頁</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'>$i</option>\n"; 
} 
} // Page分頁函數(shù) 
// 使用示例 
if (!$conn= mysql_connect("localhost", "root" ,"root")) die('數(shù)據(jù)庫選擇失??！'); 
if (!mysql_select_db("test", $conn)) die('數(shù)據(jù)庫選擇失??！'); 
mysql_query('set names GBK'); 
// 用Page函數(shù)計(jì)算出 $select_from 從哪條記錄開始檢索、$pagenav 輸出分頁導(dǎo)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; 
?> 

瀏覽 index.php 頁面，如圖：

該說byebye了，確實(shí)好用！

PHP簡單分頁函數(shù)
寫了一個(gè)php簡單的分頁函數(shù)，數(shù)據(jù)庫調(diào)用也寫到里面了，用的人可以自行刪減！

復(fù)制代碼代碼如下:

 
function getask(){ 
$sql = "select * from cms_ask where ansower <> ' ' "; 
//這里要改成方法 
$q_sq = mysql_query($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 $v){ 
echo '<dl><dt>問：'.$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; 
}
