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):
复制代码 代码如下:
// 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 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 .= "
首页 ";
$pagenav .= "
前一页 ";
$pagenav .= "
后一页 ";
$pagenav .= "
末页 ";
$pagenav.=" 跳到
\n"; for($i=1;$iif($i==$page) $pagenav.="$i \n"; else $pagenav.="$i \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] "; } 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!
复制代码 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 $page_start = 1;
$page_end = 5;
}
if ($page_current > $page_count - 4) {
$page_start = $page_count - 8;
$page_end = $page_count;
}
if ($page_start $page_start = 1;
if ($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 $v){
echo '
问:'.$v["question"].'
答:'.$v["ansower"].date("Y-m-d H:i:s",$v["postTime"]).'
';
}
$pagebar .= "
";
$pagebar .= "
"; if ($page_current != 1) { $pagebar .= 'FIRST '; } for ($i = $page_start; $i if ($i == $page_current) { $pagebar .= "" . $i . " "; } else { $pagebar .= "" . $i . " "; } } if ($page_current != $page_count) { $pagebar .= "END "; } $pagebar .= " ";
$pagebar .= "
";
echo $pagebar;
