Re: [RFC] Reflection for references

Hi! > I'd like to propose the addition of a ReflectionReference class, as > described in the following RFC: > https://wiki.php.net/rfc/reference_reflection Do I understand correctly that the main use case here is to know if two variables (treating this term expansively) point, by reference, to the same zval/location? If so, I'd probably prefer a function that gives answer to exactly this question. Currently proposed API sounds a bit weird to me - why it's only constructed from array element? It looks like a strange limitation. Additionally, I'm not sure I understand whether there's a case for "knowing whether array element is a reference to something" without it being the use case above (i.e. comparing two things). I have no idea what VarCloner does so it would be useful to have some clarity there. > The TL;DR is that some libraries need a way to detect references and > determine whether two references are the same. They previously used an ugly Is this the same case or two different cases? Also, why do they need to do it - what they are doing with this information afterwards? -- Stas Malyshev smalyshev@gmail.com
