Depends what you mean by "some wrong output". I suppose this "wrong
output" should tell you all you need. (Error reporting is activated, I
assume...)

How do is PHP supposed to know about a JS variable? In this case the
server-side PHP assumes that my_url is a constant, which it won't find
(and issue a warning).
You'd have to send your JS value to the server, have it processed there
and work with the response. Though it escapes me, why you'd like to
encode a URI, which is already on the page - plain and un-encoded.

It might be useful to know the differnce between server-side and
client-side scripting.
