I think that in the global $_POST that PHP should not convert my "." to "_" automatically.
Eg. I had a form and posted a form element with id="calendar.defaultview", and I'd like to be able to access that with $_POST["calendar.defaultview"].
I realize that it would be inconsistent with the variable name if register_globals is on, but now that its being deprecated, this deserves another look.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

PHP variable do not support '.' characters in their name, therefor '.' cannot appear as is inside variables passed via GET/POST/COOKIE/ENV.

I think this deserves another look.
If the reason that . get converted to _ is because of variable names (happens with register_globals = on) and register_globals is being recommended to be OFF, then it seems logical to me that I should be allowed to access my variables as $_POST["variable.name"]
Please allow someone else to look at this.  I'd like a second opinion on this bug.  (If two people say that it shouldn't be, then I'll be OK with that.  However, I think this is a good idea, and IS a bug in PHP, or will be when register_globals won't even be allowed (hopefully soon!)) I've also posted a message to php.dev for a discussion.

I'm negative on this changes too, it will be inconsistent with when you have register_globals on. Also, allowing this will break scripts that use images for 'submit' buttons. (It's send as image.x by the browser, while PHP makes it image_x).
