Phenixcrib Glossary: what is HHVM

HHVM

HipHop Virtual Machine ( HHVM ) is an open-source
virtual machine based on just-in-time (JIT) compilation that serves as an execution engine for the PHP and Hack programming language. By using the principle of JIT compilation, executed PHP or Hack code is first transformed into intermediate HipHop bytecode ( HHBC), which is then dynamically translated into x86-64 machine code , optimized, and natively executed.

HHVM is developed by Facebook, with the project's source code hosted on GitHub; it is licensed under the terms of the PHP License and Zend License .
