I suspect that basically the browsers say that if the attribute equals "post" then send via POST; otherwise send via GET. As I understand it, the PUT method is for sending a document to be stored at the requested URI. As such, a PHP script couldn't really be handling a PUT request because if the URI for the script exists, the content in the PUT request should replace the content of the URI. (I guess technically you might be able to swing it through something with mod_rewrite where a PHP script could handle the logic of storing (PUT) or retrieving (GET) the document.) http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.6 "The fundamental difference between the POST and PUT requests is reflected in the different meaning of the Request-URI. The URI in a POST request identifies the resource that will handle the enclosed entity. That resource might be a data-accepting process, a gateway to some other protocol, or a separate entity that accepts annotations. In contrast, the URI in a PUT request identifies the entity enclosed with the request -- the user agent knows what URI is intended and the server MUST NOT attempt to apply the request to some other resource. If the server desires that the request be applied to a different URI, it MUST send a 301 (Moved Permanently) response; the user agent MAY then make its own decision regarding whether or not to redirect the request." Secondly, there isn't a $_PUT superglobal in PHP. http://us3.php.net/manual/en/reserved.variables.php Andrew -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
