I found this in the php-manual:

To encode a '+' (plus) symbol so it ends up as '+' when decoded
automatically by PHP, you have to do this:

rawurlencode(rawurlencode("+"));

If you just call rawurlencode() once, the resulting "%2B" is converted
to '+' before '+' symbols are converted to spaces, which is not very
useful.

Give it a try...

You are not sending a + character to the script. You are sending a space to
the script. Special characters like spaces get encoded so that they are
safe for transport across HTTP. Your script is seeing the data you sent
it, not the raw encoded form.

When you create links with non-hardcoded data in the query string, make sure
you run urlencode() over the data you are supplying:

echo("http://www.example.com/test.php?t=" . urlencode($data));

(Also, somebody owns the test.com domain, example.com is reserved
specifically for this purpose).

Client-side scripting is unreliable. Plenty of people have javascript
unavailable, for all sorts of reasons.
