Problem with extending classes.

["Shaw, Chris - Accenture" <cshaw@xxxxxxxxxx>]

Hello,

Been playing around with classes in php5, extending a base class and using a
constructor etc..

But I seem to have a problem with getting the variables outside the class.
In test1.txt, I cannot anything when I access the public variables for the
class.

In test2, when I make $contact into $contactcontact, I get the values for the
variables, but it looks like all the variables in that class reference
$contactcontact when you try to access them outside the class.

Have I missed something or is there bugs with extending classes in php5?
Does this happen in php4.3?

Thanks for any help.

Chris.
