*Passing* by value or by reference has to do with function parameters, not array values. However you can assign one variable as a reference to another, see http://www.php.net/manual/en/language.references.php. When you enter a line of code like: $_SESSION['order'] = $order; you are doing a regular assignment. To use a reference instead, use: $_SESSION['order'] =& $order; The data will be passed this way to the next session. For example, try this (substitute your server name in the header() call): test1.php: <?php session_start(); $test1 = ""; $_SESSION["Test1"] =& $test1; $test1 = "this is test1"; header("Location: http://localhost/olm/test2.php";); ?> test2.php: <?php session_start(); var_dump($_SESSION); ?> The output on the second page will be something like this (I'm using xdebug so this is not raw var_dump() output): array 'Test1' => 'this is test1' -- Tom -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
