SESSION_RESET(3) 1 SESSION_RESET(3)session_reset - Re-initialize session array with original valuesSYNOPSIS
void session_reset (void )
DESCRIPTION session_reset(3) reinitializes a session with original values stored in session storage. This function requires an active session and dis-
cards changes in $_SESSION.
RETURN VALUES

SESSION_REGISTER(3) 1 SESSION_REGISTER(3)session_register - Register one or more global variables with the current sessionSYNOPSIS
bool session_register (mixed $name, [mixed $...])
DESCRIPTION session_register(3) accepts a variable number of arguments, any of which can be either a string holding the name of a variable or an array
consisting of variable names or other arrays. For each name, session_register(3) registers the global variable with that name in the cur-
rent session.
You can also create a session variable by simply setting the appropriate member of the $_SESSION or $HTTP_SESSION_VARS (PHP < 4.1.0)
array.
<?php
// Use of session_register() is deprecated
$barney = "A big purple dinosaur.";
session_register("barney");
// Use of $_SESSION is preferred, as of PHP 4.1.0
$_SESSION["zim"] = "An invader from another planet.";
// The old way was to use $HTTP_SESSION_VARS
$HTTP_SESSION_VARS["spongebob"] = "He's got square pants.";
?>
If session_start(3) was not called before this function is called, an implicit call to session_start(3) with no parameters will be made.
$_SESSION does not mimic this behavior and requires session_start(3) before use.
Warning
This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.
PARAMETERS
o $name
- A string holding the name of a variable or an array consisting of variable names or other arrays.
o $...
-
RETURN VALUES
Returns TRUE on success or FALSE on failure.
NOTES
Caution
If you want your script to work regardless of register_globals, you need to instead use the $_SESSION array as $_SESSION entries
are automatically registered. If your script uses session_register(3), it will not work in environments where the PHP directive reg-
ister_globals is disabled.
Note
register_globals: important note
As of PHP 4.2.0, the default value for the PHP directive register_globals is
off. The PHP community discourages developers from relying on this directive, and encourages the use of other means, such as the
superglobals.
Caution
This registers a global variable. If you want to register a session variable from within a function, you need to make sure to make
it global using the global keyword or the $GLOBALS[] array, or use the special session arrays as noted below.
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).
Note
It is currently impossible to register resource variables in a session. For example, you cannot create a connection to a database
and store the connection id as a session variable and expect the connection to still be valid the next time the session is restored.
PHP functions that return a resource are identified by having a return type of resource in their function definition. A list of
functions that return resources are available in the resource types appendix.
If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, assign values to $_SESSION. For example: $_SESSION['var'] =
'ABC';
