Thanks very much for the help - both methods work fine. I'd had a look at the array_walk manual, but didn't realise that the second param would accept an array - that's really cool

indeed that page does not make it very clear, it's the generic call_back syntax, which can be used practically everywhere a callback function is expected, the array you pass can be in the form of: array($object, 'methodname') or array('classname', 'methodname') the second version allows you to use static class methods.
