Max,
Thanks for your response.
Assigning something to $d->somevar when it is not declared in the
definition works fine.
As far as I can tell, and from what we have found here, there is
absolutly no reason whatsoever to define variables in class definitions.
If someone can show me me a reason , other than a pure aesthetics,
why this is nessesary I would sure like to know. If anyone could
show me at least one example where not defining variables in class
definitions would somehow break the class, I would like to see it.
Thanks,
Sam

$d->somevar3 = "value of somevar3<br>";
echo $d->somevar2;
echo $d->somevar3;
try to assign something to $d->somevar if it is not declared in the
definition.

bad practice anyway
