The problem is, is that you are not getting
A
when you submit your form.
It is being URL encoded by the browser and you are actually getting
 %20 %20 %20 A %20 %20 %20 
So, what you need to do is this
$submit = urldecode($submit);// This will take care of the %20 for spaces
$submit = str_replace(' ','',$submit); // This takes out the encoded
entities
That should take care of your problem.
Here is a note from teh html_entity_decode page:
Note: You might wonder why trim(html_entity_decode(' ')); doesn't reduce
the string to an empty
string, that's because the ' ' entity is not ASCII code 32 (which is
stripped by trim()) but
ASCII code 160 (0xa0) in the default ISO 8859-1 characterset.
/note
So, you might try replacing the with ASCII 160 char. I found that if
you hold down the alt
key and press 160 on your keyboard, it will create that char for you. you
could also do a chr(160)
and get it in PHP.
