Istoricul schimbărilor

Versiune	Descriere
7.2.0	The return type of this function is bool now. Formerly, it has been void.

Note

Notă:
If $_SESSION is used, use unset() to unregister a session variable, i.e. unset ($_SESSION['varname']);.

Precauţie

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.
