display PHP object fields in code explorer

[ggiunta]

For PHP code, no members of objects are shown by default in the code explorer panel, except for functions.
If the option 'list variables' is enabled, all php vars used within that class code are shown.
But, even if it is always possible to add members to objects at runtime, it is quite custom to declare member variables of classes using the 'var' syntax within the class definition.
I think those member variables should always be visible as part of the object hierarchy, even when 'list variables' is off.

Thanks
