Implementation of 10 pages of forward 10 pages backward 10 pages of processing

/*==== the record of the data is paginated =====
A page that has a contiguous 10-page connection
One page to display $limit_row record information
and has the next 10 page and the 10 page paging function
===================================

------need to pass in value $total_row; $limit _row; $pagename;-----
$total _row The total number of rows for the selected query result
$limit _row The maximum number of rows to display per page
$pagename Displays the page name for the return. (without suffix name)
----------------------------------------------------

----------------------------------------------------
$page the currently read page
$total _page can be divided into several pages.
$row _begin to start reading from the first few lines
$row _end to read the first line
