On the same page, I have two tables that need to be paged. when I instantiate the same paging class, the problem occurs.

On the same page, I have two tables that need to be paged. when I instantiate the same paging class, a problem occurs. I have two tables on the same page, both of which need to be paged. I have a paging class, this class is instantiated in both tables, but there is a problem after pages are turned over. no data is available. why? I instantiate it like this: $ my_page1 = new & nbsp; PageClas for the first table. on the same page, I have two tables that need pagination. when I instantiate the same pagination class, a problem occurs.
I have two tables on the same page, all requiring pagination. I have a paging class, and both tables instantiate this class. However, after turning pages, there is a problem and no data, why?
I instantiate it like this:
In the first table:

$my_page1=new PageClass($total1,20,$_GET['page'],'?account='.$_SESSION['account'].'&act=wyxx&page={page}');

In the second table:

$my_page2=new PageClass($total2,20,$_GET['page'],'?account='.$_SESSION['account'].'&act=blnr&page={page}');

The paging class is like this:

Class PageClass
{
Private $ myde_count; // total number of records
Public $ myde_size; // number of records per page
Private $ myde_page; // current page
Private $ myde_page_count; // total number of pages
Private $ page_url; // page url
Private $ page_ I; // Start Page
Private $ page_ub; // end page
Public $ page_limit;

Function _ construct ($ myde_count = 0, $ myde_size = 1, $ myde_page = 1, $ page_url) // Constructor
{
$ This-> myde_count = $ this-> numeric ($ myde_count );
$ This-> myde_size = $ this-> numeric ($ myde_size );
$ This-> myde_page = $ this-> numeric ($ myde_page );
$ This-> page_limit = ($ this-> myde_page * $ this-> myde_size)-$ this-> myde_size; // start record of the next page
$ This-> page_url = $ page_url; // connection address
If ($ this-> myde_page <1) $ this-> myde_page = 1; // when the current page is smaller than 1, the value is assigned to 1.
If ($ this-> myde_count <0) $ this-> myde_page = 0;
$ This-> myde_page_count = ceil ($ this-> myde_count/$ this-> myde_size); // The total number of pages
If ($ this-> myde_page_count <1)
$ This-> myde_page_count = 1;
If ($ this-> myde_page> $ this-> myde_page_count)
$ This-> myde_page = $ this-> myde_page_count;
// $ This-> page_ I = $ this-> myde_page-2;
$ This-> page_ I =$ this-> myde_page-2;
$ This-> page_ub = $ this-> myde_page + 2;
// $ This-> page_ub = $ this-> myde_page + 2;
If ($ this-> page_ I <1) $ this-> page_ I = 1;
If ($ this-> page_ub> $ this-> myde_page_count) {$ this-> page_ub = $ this-> myde_page_count ;}
}
Private function numeric ($ id) // determines whether it is a number.
