OKAY. Let's clarify.
Here's the string in HTML:
A
The browser then passes it to GET/POST. It decodes the entities, and
then urlencodes them. Now it looks like this:
%a0%20%a0%20%a0%20%a0A%a0%20%a0%20%a0%20%a0
Then PHP receives it, urldecodes the string, then stuffs it inside
$_POST, $_GET, $_REQUEST, etc. Now it's like this:
A
$_POST['submit'] == ' A ' // TRUE.
... *pokes my solution*...
$value = trim($value, chr(32) . chr(160));
