摘要：HipHop compiler is PHP based compiler created by facebook in order to optimize the php code and save resources on the facebook server. HPHPc translates the php code into executable c++ code. Later facebook realized that HPHPc had some snags which included resource consumption and parallel maintenance of HPHP and HPHPi. In order to overcome the drawbacks of HPHPc HipHop virtual machine was developed in 2011 which is a process virtual machine based on just-in-time (JIT) compilation, serving as an execution engine for PHP and Hack programming languages. HHVM provides complete support for the entire PHP language. This paper shows how HHVM is superior to other compilers like PHP, PHP 7 and how various framework uses HHVM to optimize php. In addition the lock-down approach shows the behavior of each framework with hhvm and s how how performance optimization can be obtained for heavy websites.
