session_register() 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() registers the global variable with that name in the current session.

This function returns TRUE when all of the variables are successfully registered with the session.
If session_start() was not called before this function
is called, an implicit call to session_start() with no
parameters will be made. $_SESSION
does not mimic
this behavior and requires session_start() before use.
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.

Bemærk: 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';
