---|---|
7.2.0 | The return type of this function is bool now. Formerly, it has been void. |
Notă:
If $_SESSION is used, use unset() to unregister a session variable, i.e.
unset ($_SESSION['varname']);
.
Do NOT unset the whole $_SESSION with
unset($_SESSION)
as this will disable the registering
of session variables through the $_SESSION superglobal.
Notă:
Only use session_unset() for older deprecated code that does not use $_SESSION.
