PHP分页函数代码（简单实用型）

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）：

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 <= 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 .= "首页 ";
$pagenav .= "前一页 ";
$pagenav .= "后一页 ";
$pagenav .= "末页";
$pagenav.="　跳到\n";
for($i=1;$i<=$page_count;$i++){
if($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;
?>

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！

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 <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 '

问：'.$v["question"].'

答：'.$v["ansower"].date("Y-m-d H:i:s",$v["postTime"]).'

';

}

$pagebar .= "

";
$pagebar .= "

";
if ($page_current != 1) {
$pagebar .= '
1. FIRST
';
}
for ($i = $page_start; $i <= $page_end; $i++) {
if ($i == $page_current) {
$pagebar .= "
2. " . $i . "
";
} else {
$pagebar .= "
3. " . $i . "
";
}
}

if ($page_current != $page_count) {
$pagebar .= "
4. END
";
}
$pagebar .= "

";
$pagebar .= "

";
echo $pagebar;
}
