Subject: GET/POST whitespace stripping behavior
From: chrislist@de-punkt.de (Christopher Kunz)

Hi,

I have a general question in regard to the PHP variable normalizing. Obviously, 
leading whitespace in a variable is stripped, but why is trailing whitespace 
converted to underscores?

Example:

/?foo=bar&+fooo=blah&foooooo+=ljalskdf

results in:

array(3) {
   ["foo"]=>
   string(3) "bar"
   ["fooo"]=>
   string(4) "blah"
   ["foooooo_"]=>
   string(8) "ljalskdf"
}

I can understand why one would want to convert middle spaces (like in "foo+bar") 
to underscores, but shouldn't trailing spaces be stripped instead? Am I missing 
something?

Regards,
