Question

I have a global object, a “registry”, it is a container with other important objects:

• Input object.
• Output object.
• DB object with connection.
• Logging object.
• Session object.

I need to have this global object in every place (object), where I process my request.

Like in my JBoss environment, where I have one Stateful Session Bean as a front controller, which directs the processing to a special Stateless Session Bean, I have one entry point, “facade.php”.

In this facade.php, I create the global object and place the other objects (input object, …) into it.

Then there is a large switch statement, where I redirect the request to special processing objects.

Is there a method, mechanism, to have access to this general object from the processing objects without handing it over as a parameter?

Answer 1

To have a variable available everywhere you can use a $_SESSION variable like so:

session_start();
$_SESSION['registry'] = // Your data

Make sure to use the session_start() function whenever you want access to the session variables.
