PHP分页入门实例 附php函数代码

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： 11小强 20小红 30小丽 41小兵 51张三 60李四 70吴欣

写PHP语句（index.php）：```php <?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！```php
    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;
    }
