anyone have HTML snippet example of HTTP method = put?

I have this: <form method="PUT" action="work.php"> File: <input type="file" /> <input type="submit" value="Submit" /> </form> Looking in my webserver logs, it changes that to a GET. Ideas anyone? The receiver is PHP and I am pretty sure I know how to handle it once it is properly PUT-ted. (I run nginx for the server and have enabled PUT as a method, supposedly) Maybe I need to do something different on the web form though? thanks!
