__construct is a subpages constructor that is used to run automatically when a class is created.
@ $each _disnums The number of entries displayed per page
@nums Total number of entries
@current_num the currently selected page
@sub_pages number of pages per display
@subPage_link links for each page
@subPage_type show the type of paging
When @subpage_type=1 is the normal paging mode
Example: A total of 4,523 records, each page shows 10, the current 1th/453 page [first] [prev] [next] [last page]
When @subpage_type=2 is a classic page-out style
Example: Current 1th 453 page [first] [prev] 1 2 3 4 5 6 7 8 9 10 [next] [last]
