Php paging code

A very exquisite php paging class that can be directly applied to the paging system is a necessary tool for mysql database paging, you only need to embed class files and paging CSS styles to achieve exquisite paging. This is a simple, convenient, and fully functional paging class. you can change the CSS style file as needed to control the page color. using the php paging class, you can save yourself a lot of time, you only need to embed it in the paging area. The following describes how to use it:

1. wrap pager.css in the headers

2. instantiate the class on the page:

 GetPagerContent();      //echo $pageStr;         $myPage=new pager(90,intval($CurrentPage));          $pageStr= $myPage->GetPagerContent();      echo $pageStr;        ?>

3. read mysql databases and paging computing files by yourself. For example:

$ Info = mysql_query ("select * from member order by id desc limit $ offset, $ info_num"); in this way, it can be transferred to the mysql database and the current page number.

The following are a total of three files: (1) index. php: Call the paging class, display the page (2) pager. class. php: php paging class (3366pager.css: css style beautification file

(1) index. php:

    
     ---- Paging demonstration -----    
                 
 GetPagerContent (); // echo $ pageStr; $ myPage = new pager (90, intval ($ CurrentPage); $ pageStr = $ myPage-> GetPagerContent (); echo $ pageStr;?>    

(2) pager. class. php:

 GetPagerContent (); echo $ pageStr; */class Pager {private $ pageSize = 10; private $ pageIndex; private $ totalNum; private $ totalPagesCount; private $ pageUrl; private static $ _ instance; public function _ construct ($ p_totalNum, $ p_pageIndex, $ p_pageSize = 10, $ p_initNum = 3, $ p_initMaxNum = 5) {if (!
