I have seen a few paging classes before, it is relatively complicated, and I can't understand those code, and I found that when I want to query the data in a composite condition, it is very difficult. So I want to write one yourself. For five months of using PHP, I just seem to understand for the concept and use of the class. This is the first time I wrote the class - page navigation class, I hope to have a new hand, there is also a phper like me! ! / * _________________________________ CLASS NAME: SHOWPAGE _________________________________ Copyright (c): ERLDY (scarecrow) Author: Arvan [E-mail: erldy@126.com QQ: 103808353] Create date: 2004-09-27 ________________________________ * / / ***** Example: $ SQL = "Select Count (*) As Count from $ TBL"; $ DB-> Query; $ db-> next_record (); $ count = $ db-> f (count); // Total number $ page = new showpage; $ page-> Total = $ count; $ page-> linkary = array (); // use array ("ID" => $ ID) this Array deliver URL variable $ sql = "Select * from $ TBL Order by Sortid Desc Limit". $ Page-> offset (); $ db-> query ($ sql); $ showpage = $ page-> showlink ();
