HHVM, the new PHP?
summary
HHVM is a drop-in alternative runtime that replaces the Zend engine with JIT compilation to compile PHP to machine code, promising big resource savings (Facebook reports up to an eightfold reduction, typical cases claim ~20–30%) and faster steady-state execution after warmup. Earlier HipHop compiled PHP to C++ producing 1 GB monolith and deployment headaches, so Facebook built Hack gradual typing on top of HHVM to enable static analysis and safer large codebases. Watch for missing extensions, Windows immaturity, and possible community fragmentation.
