> 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.

You can't store database connections in a session.
Ie you can't:
$connection = mysql_connect(....);
$_SESSION['DbConnection'] = $connection;
because the HTTP protocol (and thus PHP) is stateless - you don't know
where the next connection is coming from or even if there is another
connection coming.
If there is another HTTP request, you have no way of linking request '1'
(where the database connection was set up) to request '47' in the chain.
