New Comment:
If, aside from backward compatibility, there are no disadvantages to
fixing this bug, wouldn't it be easy enough to have both versions of the
variable in the superglobal array to make the fix backward compatible?
Also, in response to Michael: right, the sample code is not real life
code obviously :) The reason I am using variable names with spaces and
periods is that the variable names are autogenerated based on page
titles and filenames. I figured out a way around it easily enough -
after I figured out what was happening. But it took me a while to
figure it out with the documentation not mentioning it!
I just think if there's no reason not to, it would sure make things
easier to keep the indices unaltered whenever possible.

This can't be fixed without breaking application relying on that
feature.

G'day
Why dont you just call it 'title' then:
<?
if(!empty($_POST['title']))
echo $_POST['title'];
?>
you can even make them an array eg.
<form method="post">
<input name="title[]" type="text">
<input type="submit">
</form>
<?
if( (!empty($_POST['title'])) && is_array($_POST['title']))
{
foreach($_POST['title'] AS $title)
echo $title,'<br>';
}
?>
You should be escaping the output for real life code but I'm sure you
knew that ;)

Description:
------------
I think it would make more sense if PHP only replaced '.' and ' ' with
'_' when register_globals is turned on, and only for the variables that
are registered in the global scope, leaving the superglobals' index
names as they are.
I understand that variable names can't have '.' or ' ' in them, however
it seems that most people use the $_POST['variablename'] method of
accessing external variables, and in this case, the spaces and dots make
no difference.
I could find practically no reference to this behavior in the manual,
other than a couple notes I submitted. At the very least, the fact that
these characters are replaced should be made more obvious in the manual
under "Predefined Variables" at
http://us2.php.net/manual/en/language.variables.predefined.php and
http://us2.php.net/manual/en/reserved.variables.php
Reproduce code:
---------------
<form method="post">
<input name="title for page3.php" type="text">
<input type="submit">
</form>
Title submitted:
<?php
if (count($_POST) > 0)
echo $_POST['title for page3.php'];
?>
Expected result:
----------------
I expect to see the title I submitted print out.
Actual result:
--------------
The POST key 'title for page3.php' is changed to 'title_for_page3_php',
and nothing prints out.
