Realize the processing of ten pages forward and ten pages back_PHP tutorial

/*==== Display data records in pages =====
One page has ten consecutive page connections
One page can display $limit_row record information
It also has the function of turning the next ten pages and the previous ten pages
================================== ===

------You need to pass in the value $total_row;$limit_row;$pagename;-----
$total_row is the total number of rows in the selected query results
$ limit_row is the maximum number of rows displayed on each page
$pagename is the name of the returned display page. (without suffix)
----------------------------------------- ----------

--------------------------------- -------------------
$page The page currently being read
$total_page is the number of pages that can be divided into.
$row_begin is the starting number Start reading the row
$row_end is the number of rows read
-------------------------------- ---------------------*/
