No, a zval (which might point to a hash tale) doesn't refer to a name. For one there in 99.99% is no need but it would cost memory(and CPU cycles to maintain) and then there miht e multiple nae (references) or none (temporaries etc.) If you know the parent such hacks like > https://gist.github.com/krakjoe/50603be7ffb1ae6e9156 might work, but even this solution is flawed: The easy thing it doesn't support is references, it should return an array of all names. It won't work for complex things, though. If you need such a functionality I'd suggest to take a step back and think what you actually want to do ... usually there is a better solution. johannes
