详细信息是：
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


我在网上查找资料，大多答案是不要用session_register()方法就可以。

问题时我完全没有使用session_register()方法，直接使用$_SESSION[ 'XX ']=$XX   的方法，依然出现此警告，如何解决？
