register globals is no longer used in php
the above post simply explains that sometimes if your version still uses it, that the variable is written 2x in the php.ini and will work normally if the second instance is removed....
see its also written in htaccess 2x if you use php4 and php5 open it and see what i mean??
you can verify its off by going to administration/phpinfo.php and seeing the section for register globals..it will actually be off...so no need for these dummy lines.
if you do see that the master settings for "register_globals" is on then your htaccess file will be neeeded...depending on your server...test by changing values from ON to Off in htacces
the left side will change upon refresh
most often hosts will help you out and change master values for you if you ask nice enough...
