session_unregister
(PHP 4, PHP 5)
session_unregister — Unregister a global variable from the current session
Description
bool session_unregister
( string $name
)
Parameters
-
name
-
The variable name.
Return Values
Returns TRUE on success or FALSE on failure.
Notes
Note:
If $_SESSION (or $HTTP_SESSION_VARS
for PHP 4.0.6 or less) is used, use unset() to
unregister a session variable. Do not unset()
$_SESSION itself as this will disable the special
function of the $_SESSION superglobal.
Caution
This function does not unset the corresponding global variable for
name
, it only prevents the variable from being
saved as part of the session. You must call unset()
to remove the corresponding global variable.
