That's fine for me. I did not know that, so I used the site name as key,
which worked fine until I updated PHP, then suddenly this happened.

I'm not too sure how or why this would have worked in 5.2, but session
variables not being able to use certain characters in their names is
documented behaviour, per http://php.net/session.examples.basic ââ:
"The keys in the $_SESSION associative array are subject to the same
limitations as regular variable names in PHP, i.e. they cannot start
with a number and must start with a letter or underscore. For more
details see the section on variables in this manual."

Description:
------------
Array keys in $_SESSION containing exclamation marks (!) does not seem
to work anymore as of 5.3.3.
Have tried key with different characters like #, " and £ - these
worked. Using "!" in the key seems not only to be unregistered but also
to make the whole $_SESSION to be unset in the next run.
This worked before, as in 5.2.x.
Test script:
---------------
<?
# (as we're talking sessions, this example need to be run 2 times to
set the session data, push F5...)
session_start();
$name = 'hello'; # this does work, uncomment/comment to test
$name = 'hello!'; # this does not, uncomment/comment to test
echo $_SESSION[$name];
$_SESSION[$name] = 'OK';
?>
Expected result:
----------------
That array keys containing exclamation marks ("!") either give a
understandable error or does work as any other key.
Actual result:
--------------
The whole array is being totally empty if a key containing exclamation
mark is entered.
