Of course the tests could easily be regular expressions (but in your example prabaly not needed. Personally id stick all the allowed users in an array or a DB table and check against that. eg: $users["foo"] = true; $users["bar"] = true; $users["me"] = true; $users["you"] = true; if($users[$login] != true){ echo "Not allowed"; exit(); } Bit more extensible...

For example, with Perl I was able to restrict access to certain pages using something like this: $login = $ENV{REMOTE_USER}; unless ($login =~ /^foo$|^bar$/) { print $query->redirect("../no_access.html"); } or - If I had a form with many fields I could do something to the effect of unless ($field1 && $field2 && $field3 && $field4 && $field5) { print "you did not complete all fields.\n"; } can someone please enlighten me as to how I could achieve this same functionality within PHP? I've searched through several books to no avail - the only thing I could find remotely similar was the "isset" function but that only seems to work with a single value and not groups. Any help would be greatly appreciated. I'd hate to have to go back to Perl so soon in the game ;) Brian
