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
