Could you solve it with this?: I think you have to also define the arguments you want to use for item() in your interface: function item($a_iIndex); Regards, Torsten Roehr -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Are you sure you need '' here? Shouldn't PHP5 pass all variables by
reference on default?

The -operator is still important in PHP5. Look at the folling example
?
$a = new stdclass;
$b = $a;
$c = $a;
?
unsetting a will only kill a, b and c will still be alive.
setting a to null will kill c but not b

you could however always call:
$a-__destruct();
that would also kill $b and $c
