PHP Classic pagination classes apply to all pagination

Classic PHP Tutorial Page class-PHP General Page class

private $nums//Total number of entries

Private $sub _pages;//The number of pages per display

of pagination

    /* 


__construct is a subpages constructor that runs automatically when a class is created.


@ $each _disnums The number of entries displayed per page


@nums Total number of entries


@current_num currently selected page


@sub_pages number of pages per display


@subPage_link links for each page


@subPage_type Display the type of pagination


 


when @subpage_type=1 for general paging mode


Example: Total 4,523 records, each page shows 10, the current 1th 453 page [first] [prev] [Next page] [last page]


The classic paging style when @subpage_type=2


Example: Current 1th 453 page [first] [prev] 1 2 3 4 5 6 7 8 9 10 [next page] [last]
