Примітки

Зауваження:

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.

Застереження

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.

Застереження

If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().

If globals is on, you'll have to unset the $_SESSION[varname] as well as the $varname.

Like:

unset($_SESSION[varname]);
unset($varname);

To unregister some session you can use:

<?php
// delete session
$_SESSION['NAME'] = array();

// start session
session_start();

// put info in session
$_SESSION['NAME']['userid'] = 5;
$_SESSION['NAME']['name'] "John Doe";
?>

as a side note you must have session_start() set inorder to actually unregister the session varibles.
