' href= ' behind, '? ' If you don't add anything to the front,

This is on the pagination.

  
   =$e_page)?$page:($page+1);$html.='next'.' ';$html.='end'.' ';return $html;}?>

Please look at line fourth, there is nothing in front of the question mark, normal should not have an address code? Why is there nothing here?
(I think the meaning may refer to the current page, but the current page is not a #?) ）

The current page, but with one more page parameter

"#" is actually the anchor tag prefix instead of the current page, the professional noun called the page hash, the browser's return button also use this for Web content positioning, but also support JS on the location of the Web page

Click the Specify href= "#content" link, you can navigate to the location of the Hello World label, if only # then locate the top, you will find that the page is not refreshed

But if the href is empty, navigate to the current page.

If the current page address is

http://www.xxx.com/a.php?b=1&c=2

So, on this page,
???
Jump to the page is
http://www.xxx.com/a.php?d=1
