send command:
nano /etc/php.ini
now look for this line:
register_globals = Off
Change it to:
register_globals = On
restart apache server with this command:
/etc/init.d/httpd restart
that's it - NOTE: by enabling register_globals your server will be less secured, read this:
; Whether or not to register the EGPCS variables as global variables. You may
; want to turn this off if you don't want to clutter your scripts' global scope
; with user data. This makes most sense when coupled with track_vars - in which
; case you can access all of the GPC variables through the $HTTP_*_VARS[],
; variables.
;
; You should do your best to write your scripts so that they do not require
; register_globals to be on; Using form variables as globals can easily lead
; to possible security problems, if the code is not very well thought of.
