Since register_globals has been removed in PHP 5.4.0 there should be no reason other than legacy why input variables ($_POST, $_GET, $_FILES, $_COOKIE, $_REQUEST) can not have keys containing following characters

chr(32) ( ) (space)
chr(46) (.) (dot)

Documentation states that only . is changed to _ but same goes for above characters.

Test script:
<form method="POST">
<input type="text" name="foo bar" value="spaced" />
<input type="text" name="" value="dotted" />
<input type="submit" value="send" />




  "foo bar"=>'spaced',

Actual result:

This may break apps, but request is debatable.

I'd like to second this report/request. With register_globals having been deprecated and removed quite some time ago now, it would be great to see some of the accommodations made for that feature cleaned up.

While it is perfectly understandable that this could cause BC breaks, an INI flag would certainly fix this.

; replacement altogether

This topic comes up in internals discussions from time to time.
Unless someone pursues the RFC process[1], nothing will change. :(
