session_unregister

(PHP 4, PHP 5 < 5.4.0)

session_unregister — Unregister a global variable from the current session

说明

session_unregister ( string $name ) : bool

session_unregister() unregisters the global variable named name from the current session.

Warning

本函数已自 PHP 5.3.0 起废弃并将自 PHP 5.4.0 起移除。

参数

name: The variable name.

返回值

成功时返回 TRUE，或者在失败时返回 FALSE。

注释

Note:
If $_SESSION 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.

Caution

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.
