Bug description: session_set_save_handler cann't get global variable(instance
of object)
Description:
------------
hi staff,
In my programs of my php5.3,i use function "session_set_save_handler"
to set the sessions into database,this function must set the
parameters:names of the functions like :(open,close,read,write,destroy,gc)
as string.
when i use the functions :read,write,destroy,gc ,i set a global
variable(an instance of object) in them ,but i found it works normally in
these functions except in "write";i cann't get the value of the
variable,only appears in the "wirte" function.
i change the version of php to < 5.3 like :4.x ¡¢5.2, the problem above
disappears.
i don't know the reason.can you help me to find it out?
