Hi,
first of all I want to say that I am just a newbie in PHP. I am switching to PHP from other languages and I am exploring how PHP manages references. To do that I am gathering information about what happens with Symbol Tables and Variables Containers when using references. You know: reference-counting, copy-on-write and all that stuff...
I found out some cases where I think that some Variable Containers copies could be skipped, thus saving memory and improving performance relying in the copy-on-write principle. I wrote a PDF trying to explain what I mean. It is not written in a very techy language, because I am just new and don't know too much about the internals, but I hope you can understand it and post your comments.
Probably if my "update" hasn't been done yet, is because it is not possible, but I will very glad to hear your comments and learn from you.
Thank you very much.
