Because, when register_globals is set to On, the names of all GET, POST and COOKIE parameters will be used as variable names, they may only contain characters which are legal in PHP variable names. PHP automagically converts all other characters to _ on the fly as they are loaded into the $_GET, $_POST and $_COOKIE arrays and, if register_globals is set, the equivalent global variables. > So I though that you couldn't have dots in your array > names... There's no problem with this -- it's purely that GET, POST and COOKIE names must conform to PHP variable naming rules. This is documented, if somewhat minimally, at http://uk2.php.net/manual/en/language.variables.external.php#language.variab les.external.dot-in-names. Cheers!
