Php + oracle Paging

The following is a paging sample program, which may seem complicated, but you only need to use it to find that "everything is so simple ":)
Example. php
$ Conn = maid ("test", "123456", "test123 ");
Include_once "pager. inc. php ";
?>
/** Start paging test */
// {Initial paging object
$ Pager = new pager ();
/** Split select id, name, age from test where age> 20 order by id desc */
$ SqlArr = array (conn => $ conn, // Database Link
Fields => "id, name, age", // query the subject sentence
Table => "test", // table name
Condition => "age> 20", // query condition
Order => "order by id desc" // sorting method
);
If (! $ Pager-> listn ($ sqlArr, 10, $ page) // 10 entries are displayed on each page.
{
$ Pager-> errno = 10;
Die ($ pager-> errmsg ());
}
//}}}
// {Data Display
For ($ I = 0; $ I <count ($ pager-> result); $ I ++)
{
$ Tmp = $ pager-> result [$ I];
Echo "id:". $ tmp [ID]."
";
Echo "name:". $ tmp [NAME]."

";
Echo "age:". $ tmp [AGE]. ""
}
//}}}
// {Display Page Link
Echo $ pager-> page. "/". $ pager-> totalpage. "total". $ pager-> total. "record ";
If ($ pager-> prev! = 0)
Echo "prev."> previous page ";
Else
Echo "Previous Page ";
If ($ pager-> next! = 0)
Echo "next."> next page ";
Else
Echo "next page ";
//}}}
