How to avoid deprecation warning by replacing session_unregister with $SESSION[] after upgrading to PHP 5.3?

Question
I just installed PHP 5.3 and am weeding out consequent "deprecated" warnings.
It says session_unregister() is deprecated
in:
session_unregister($serverWideUniqueIdCode);
and the replacement seems to be $_SESSION[].
So what would be the syntax with $_SESSION[]
to express the same thing?
Solution
Quoting the doc (take a look at that page, it says quite some interesting stuff ;-) ) :
session_unregister() unregisters the global variable named name from the current session.
To remove an entry from an array, you can use unset
. So, instead of
session_unregister('my_var');
You can use
unset($_SESSION['my_var']);
Which, in your case, I guess, means :
unset($_SESSION[$serverWideUniqueIdCode]);
Still, you probably don't want to call unset
on the whole $_SESSION
variable. Quoting the doc a second time :
Note: If
$_SESSION
(or$HTTP_SESSION_VARS
for PHP 4.0.6 or less) is used, useunset()
to unregister a session variable. Do notunset()
$_SESSION
itself as this will disable the special function of the$_SESSION
superglobal.
OTHER TIPS
$_SESSION = array();
