Yup - you can also do that on a script level with the command: ini_set("register_globals",1); provided it's not running in safe mode. I do recommend changing your scripts over to use the new superglobal arrays though - it only need be at the start of each script, put something like $orignalvariablename=$_POST["orignalvariablename"]; for each variable you want to get from a post, likewise for get and cookies - this will give you the security advantages of knowing what the variables have been set from (the whole point behind not using register globals), and only requires a fairly small change to the script. I'm working through mine at the moment... it is taking a while, but it's worth doing IMO.
