注意: 公众号列表最多只能列出 8 列, 超出会报错
分页原理
limit 开始位置 , 条数
(当前页数 - 1) x 每页条数 , 每页条数
limit ($Page - 1) * $PageSize , $PageSize
0 为开始位置
mysql_num_rows 条数
require() 与 require_once() 开始加载, 错误停止
include() 与 include_once() 使用加载, 错误跳过
ceil 进一 向上取整
原理:
总共 10 条, 每页 9 条
n 条
sum 总共几页 ceil ( n / 9 )
开始条数 : (当前页数 - 1 ) x 每页条数
(key - 1)* 9
注释:+1 是为了说明有多少页
>10 10

coon.PHP 连接数据库代码如下:
