From PHP to Hack as a Stack and Back
summary
History of moving a PHP codebase onto HHVM and Hack with concrete migration notes: HHVM runs as a drop‑in but top‑level code must be bootstrapped (use a partial require_once file), references and eval/variable variables are unsupported, and HTML+PHP needs XHP or separate rendering. Hack’s type checker forces shapes, generics, and collections (map/vector/set/pair), so expect fewer runtime bugs but plan refactors for dynamic syntax and intrinsics.
