Speeding up the Web with PHP 7
summary
PHP 7 ships with large practical wins: 2x overall and 3x on WordPress performance and big memory cuts (example WordPress array test drops from ~43MB to ~6MB), a file-based opcache for faster restarts and CLI, an AST-based parser exposing static analysis, fatals-as-exceptions, return and scalar type hints (coercive or strict), null-coalesce and spaceship operators, zero-cost assertions, and deployment tooling shown (IRC-based deploys, mod_realpath, fan static analyzer, Vagrant images).
