    somevariable will work only with register_globals on, $_POST[variablename] will work with register_globals on or off. Since php4.2, by default, register_globals have been turned off by default. Not only is it easier to understand the code using the super globals, but it's also more secure as $_POST[variable] will only work if the form has been POSTed and can't be altered by GET or a session or whatever. (unless you've coded it to change)
