Look at the value in the session, and which page is coming in.

This should be the paging page number parameter, like this
http://index.php?n_page=2,3,4 ...
When N_page is the first page, it is usually not possible to get parameters, so you need to determine whether $_get[' n_page ' is present or not, or the first page. If present, the contents of the corresponding page are displayed according to the value obtained.

Don't you have a statement like that?
"> Home
$_get[' N_page ' This is how it came about.

What is the value of the link passed through the page?
$_get value; The default is the first page.
There's a page in the back of you!

In fact, "> Home"
This involves the knowledge of URL values, when a link is passed to the address bar $_get[] array will intercept it, because the $_get[] array is a global variable array, specifically responsible for intercepting the value in the Address bar.
It is only a pity that we have not answered it correctly.
