where I

Pauau,
Please visit the link below for help..

what you are using is potentially not what you think it is. you are using
a 'static variable' which is not a static class member.
actually it pretty much *is* the same - the static class member will exhibit the
same behaviour, only the scope is different.
you can find the
doc on static variables here,
http://www.php.net/manual/en/language.variables.scope.php
im not sure if their behavior is well defined when they are used in classes,
or objects.
behaviour is indentical to usage inside standalone functions.
as Nirmalya, has alluded, you should check out the docs on static class
members. im sure that you can achieve whatever you need to by using
some combination of static class members and instance variables.
