  <?php/*** 深入理解PHP会话控制* User: gutops*///启动新会话session_start();//设置session_namesession_name(‘PHPSESSID_NEW‘);echo session_name();    //输出为PHPSESSID_NEW

  This sesssion_name does not change, check the browser cookie name is PHPSESSID (the default setting in PHP.ini session.name)

• [Set Session_name again to start session (correct modification mode)]

<?php/** * 深入理解PHP会话控制 * User: gutops */session_name(‘PHPSESSID_NEW‘);session_start();echo session_name();    //输出为PHPSESSID_NEW
