PHP分頁函數代碼

這篇文章介紹的內容是關於PHP分頁函數代碼 ，有著一定的參考價值，現在分享給大家，有需要的朋友可以參考一下

準備資料：

建立一個資料庫 test
執行下面的語句（建立一個表 test ：id、sex、name 三個欄位）

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;

添加資料到 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）：

複製代碼 代碼如下:

<?php // Page分頁函數 $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'>後一頁</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'>$i</option>\n"; } } // Page分頁函數 // 使用樣本 if (!$conn= mysql_connect("localhost", "root" ,"root")) die('資料庫選擇失敗！'); if (!mysql_select_db("test", $conn)) die('資料庫選擇失敗！'); mysql_query('set names GBK'); // 用PageFunction Compute出 $select_from 從哪條記錄開始檢索、$pagenav 輸出分頁導航 $rows = mysql_num_rows(mysql_query("select * from test")); Page($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，

該說byebye了，確實好用！

PHP簡單分頁函數
寫了一個php簡單的分頁函數，資料庫調用也寫到裡面了 ，用的人可以自行刪減！

複製代碼 代碼如下:

function getask(){ $sql = "select * from cms_ask where ansower <> ' ' "; //這裡要改成方法 $q_sq = mysql_query($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 .= "<p 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 .= " </p>"; echo $pagebar; }
