服务器是刚配置的,使用的是PHP5 在使用session_register()函数时出现问题,提示如下:

Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0

刷新页面后恢复正常,session也使用正常, 之前开发中从未遇到这个问题,期待高人指点迷津
