Paging class code
class SubPages{
private $each_disNums;//The number of items displayed on each page
private $nums;//Total number of entries
private $current_page;//The currently selected page
private $sub_pages;//Number of pages displayed each time
private $pageNums;//Total number of pages
private $page_array = array();//used to construct an array for paging
private $subPage_link; //Link to each page
private $subPage_type;//Display the type of paging
/*
__construct is the constructor of SubPages, which is used to run automatically when creating a class.
@$each_disNums The number of items displayed on each page
@nums Total number of entries
@current_num The currently selected page
@sub_pages The number of pages displayed each time
@subPage_link Link to each page
@subPage_type Display the type of paging
When @subPage_type=1, it is normal paging mode
Example: 4523 records in total, 10 records displayed on each page, current page 1/453 [Home] [Previous page] [Next page] [Last page]
When @subPage_type=2, it is the classic paging style
Example: Current page 1/453 [Home] [Previous page] 1 2 3 4 5 6 7 8 9 10 [Next page] [Last page]
