I can't see anything in the HTML4.01 spec which forbids this. It's
valid, that's easily checkable; it also complies with at least one
reading of the prose. What's left is to see what browsers make of it.

On submission, according to the spec, a question mark is appended to the
value of the action attribute and the form data set (name/value pairs) is
then appended. Here, the action URL already has a question mark, so
appending another question mark gives a URL with two question marks, e.g.

http://host.invalid/foo?bar=1?baz=2

If arg_separator is the ampersand '&', the first and second arguments will
combine and PHP will recognise only one variable: name 'bar', value
'1?baz=2'.

As to browsers, YMMV.
