The new features of PHP 7

on YouTube ↗41m

" summary

PHP 7 (released December 2015) rewrites internals and yields big, measurable gains: an example array script drops memory use from 400MB to 53MB and execution time falls by an order of magnitude; WordPress benchmarks show double requests per second over PHP 5.6; real sites like Badoo, Tumblr and Dailymotion report halved CPU/latency or large cost savings. Language changes add scalar and return type declarations, the spaceship and null-coalescing operators, anonymous classes, Throwable error handling, random_bytes/random_int, and 7.1 brings OpenSSL AEAD (GCM/CCM) and mcrypt deprecation.
