HipHop VM (HHVM) is a virtual machine designed for executing programs written in Hack and PHP.

HipHop VM (HHVM) is a virtual machine designed to execute bytecode compiled just-in-time from both the PHP and Hack programming languages. It is maintained by Facebook.

HHVM is created as the successor of the HipHop for PHP (HPHPc) PHP execution engine, which is a PHP-to-C++ transpiler also created by Facebook. Based on the gained experience and aiming to solve issues brought by HPHPc, in early 2010 Facebook decided to create a JIT-based PHP virtual machine. Issues associated with HPHPc included its flattened curve for further performance improvements, lack of full support for the PHP language, and difficulties related to specific time- and resource-consuming development and deployment processes.

Is it possible to store HHVM bytecode as a file?

Is there a way to save HHVM bytecode as a file, since HHVM uses JIT bytecode compilation instead of compiling? If not, are there any alternatives for modern PHP versions (5.5,5.6)?
