PHP 7, 8, HHVM and other implementations and compilers like QB and Zephir provide major performance improvements and new features to PHP. PHP 7 focused on speed increases through a reworked engine and true 64-bit support. PHP 8 adds a JIT compiler for additional gains. Alternative implementations like HHVM, QB and Zephir use compilation and optimization to provide native execution speeds. Future areas of focus include extending PHP using PHP itself, and integrating other languages for extensions.
