新建一個數(shù)據(jù)庫 test
執(zhí)行下面的語句（新建一個表 test ：id、sex、name 三個字段）
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
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 共 $rows 條記錄 ";
$pagenav .= "<a href='?page=1'>首頁</a> ";
$pagenav .= "<a href='?page=$pre_page'>前一頁</a> ";
$pagenav .= "<a href='?page=$next_page'>后一頁</a> ";
$pagenav .= "<a href='?page=$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)庫選擇失敗！');
if (!mysql_select_db("test", $conn)) die('數(shù)據(jù)庫選擇失敗！');
mysql_query('set names GBK');
// 用Page函數(shù)計算出 $select_from 從哪條記錄開始檢索、$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;
?>

該說byebye了，確實好用！
php簡單分頁函數(shù)
寫了一個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;
}
