Cannot cast to a user object in PHP

Hi,

I’ve got a PHP class called User which I am using across sessions by implementing the __sleep and __wakeup methods.  The class itself is working fine, but I’ve lost introspection within the visual studio IDE as I have to get it from the session object and not via the new object keyword.

So when I do $user = new User(); code completion works fine as the IDE knows it’s a User object.

However, when I do $user = $_SESSION['user']; the IDE doesn’t know what type it is and I lose the code completion.

Does anyone know how I could get around this?

Regards

Graham

I wouldn't think you can get around this. This is because:

$_SESSION["user"] you know will be a User() object, however it has the potential to be anything else, string, integer, etc... thus the IDE cannot be sure therefore doesn't auto-complete for you.

You can always try casting, if this doesn't work then I wouldn't think there's a way to fix this.

$user = (User) $_SESSION['user'];

Hope this helps.

Yes, I tried casting, but you can't cast to a user object, which seems a bit crazy.  I think I'll raise this with Zend as a support ticket.

I got a response from Zend.  The answer is PHPDOC!

This was the solution:

**
* Returns the user object
*
* The user object contains all data about the user including the signed on flag
*
* @return       User      Returns the User object
*/
function get_user_obj() {
      if (!isset($_SESSION['user'])) {
            $_SESSION['user'] = new User();
      }
      return $_SESSION['user'];
}

$user = get_user_obj();

Now code completion with work for $user
