帝国分页查询代码

$file_page = "juhe.txt";
$num = 50;
if(file_exists($file_page)){
    $page_num = file_get_contents($file_page);
}else{
    $page_num = 0;
}
$page_id = $page_num*$num;
$next=$page_num+1;
file_put_contents($file_page,$next);

$sq l=$empire->query("SELECT * FROM `phome_ecms_news` order by `id` ASC  limit {$page_id},{$num}");
while($r=$empire->fetch($sq l)){
//分页代码
}

这段代码可以查询出分页，是PHP代码，效果就是可以把数据表里面每一页数据都给查出来
