Hi,
I'm using PHP5 and try to do something like this:
I have a base class called 'Entry' and a child class called
'ExtendedEntry'. I want to read all Entries to a certain topic from a
database.
While constructing the EntryObject I would like to look if Entry is a
simple Entry or an ExtendedEntry. I want the new object to be an
ExtendedEntry - if possible - and otherwise to be an Entry.
It was not possible to return the object in the __construct() function
and it was not possible to reassign $this with code like
$this = new ExtendedEntry()
also in the __construct() function. And I tried to always generate an
ExtendedEntry with a flag, that says it is really Extended and a
typecast afterwards, but I wasn't able to typecast to another object by
(Entry) $extEntry.
Any suggestions how to solve this problem without writing a
generateEntry() function, that looks into the database and then calls
the correct class type?
thanks in advance,
Norbert
