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

The code is as follows:

2. instantiate the class on the page:

The code is as follows:

Include "pager. class. php ";
$ CurrentPage = isset ($ _ GET ['Page'])? $ _ GET ['Page']: 1;
// Die ($ CurrentPage );
$ MyPage = new pager (1300, intval ($ CurrentPage ));
$ PageStr = $ myPage-> 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:

The code is as follows:

---- Paging demonstration -----



Include "pager. class. php ";
$ CurrentPage = isset ($ _ GET ['Page'])? $ _ GET ['Page']: 1;
// Die ($ CurrentPage );
$ MyPage = new pager (1300, intval ($ CurrentPage ));
$ PageStr = $ myPage-> GetPagerContent ();
// Echo $ pageStr;
$ MyPage = new pager (90, intval ($ CurrentPage ));
$ PageStr = $ myPage-> GetPagerContent ();
Echo $ pageStr;
?>

(2) pager. class. php:

The code is as follows:

/*

* @ Modify 2013-03-27
* @ Link https://www.php1.cn/
* Example:
$ MyPage = new Pager (1300, intval ($ CurrentPage ));
$ PageStr = $ myPage-> GetPagerContent ();
Echo $ pageStr;
