GET/POST whitespace stripping behavior View as Markdown

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,

He's asking 'why' not 'how'...
