Proposal for a RFC

Hi Internals team! I have an idea for a feature that I'd love to see in the language one day and wanted to run the idea by you all. The idea is to add a new magic method "__toArray()" that would allow a developer to specifiy how a class is cast to an array. The idea is the same mentality of __toString(), but, for arrays. I would personally love this feature and those I've run it by were also excited by the idea. So I'm soliciting feedback in hopes that things go well and I can officially write the RFC. As for implementation, Sara Golemon is awesome and while chatting a few months back, knocked out a proof-of-concept implementation <https://github.com/sgolemon/php-src/tree/experimental.toarray>. There's still work to be done if this proposal gets to the RFC phase, but again, just gauging interest here. I appreciate any feedback you all can provide. Thanks, - Steven Wade
