HHVM is a drop-in replacement for the PHP runtime, built by Facebook to improve performance and scalability and introduce the possibility of new code features to PHP. Written in C++, HHVM uses a just-in-time compiler to optimize the performance of normal PHP code -- leading to performance gains of anywhere from 50-75%. In addition, HHVM enables the use of a new dialect of PHP named Hack, which includes many new language features including static typing, generics, asynchronous I/O, and more. Come learn:
- How HHVM works and how to get it operational on your own environments
- How does HHVM stack up against PHP 5 and PHP 7, particularly when running Drupal sites
- What's under the hood -- what makes HHVM fast and who is it best for
- Hack -- language features that HHVM adds to PHP for expanded developer productivity
