SESSION_REGISTER(3)							 1						       SESSION_REGISTER(3)

session_register - Register one or more global variables with the current session

SYNOPSIS

       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';
