Given that all three of $_GET $_POST and $_COOKIE are equally suspect from a security POV, and you shouldn't really *care* which way the client delivered the value, or at least not rely on it for anything useful, I've never understood the resistance to using $_REQUEST. Yes, GET should be idempotent, but there are many APIs and functions in a large app that are idempotent by nature, and having a REST that just doesn't care how the data comes in allows the consumer of the service to use whatever they prefer. If your entire REST service is read-only, such as an RSS feed, why not allow GET or POST (or, silly as it may be COOKIE) and just use $_REQUEST. -- brain cancer update: http://richardlynch.blogspot.com/search/label/brain%20tumor Donate: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=FS9NLTNEEKWBE
