大概用法
example :
log in page : $session = session::getObject();
$session->set_ture(); // if $row['password'] ==
next page :
<div class="codetitle"><a style="CURSOR: pointer" data="1300" class="copybut" id="copybut1300" onclick="doCopy('code1300')"> 代码如下:<div class="codebody" id="code1300">
$session = session::getObject();
if($session->get_status())
// .... the user is really
else
// ....
log out : $session = session::getObject();
$session->end_session();
由get_status()返回当前用户是否有效登录 （编辑：李大同）
