session_unregister

SESSION_UNREGISTER(3)							 1						     SESSION_UNREGISTER(3)

session_unregister - Unregister a global variable from the current session

SYNOPSIS

       bool session_unregister (string	$name)

DESCRIPTION

       session_unregister(3) unregisters the global variable named $name from the current session.

       Warning

	      This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

PARAMETERS

	      o $name
		- The variable name.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

NOTES

       Note

	       If  $_SESSION  (or  $HTTP_SESSION_VARS  for  PHP  4.0.6	or  less)  is  used, use unset(3) to unregister a session variable. Do not
	      unset(3)$_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(3) to remove the corresponding global variable.

       Caution

	       If  you	are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(3), session_is_registered(3) and session_unregis-
	      ter(3).
