Q & A site template such as stackoverflow

Question

I am looking for a template for Q & A site such as stackoverflow, preferably written in PHP. Does anyone know some kind of open source template? I was already looking for github but did not find anything.

Thanks in advance.

Answer 1

I think both of them are open-source and PHP.
