What To Expect From PHP7
summary
PHP 7 delivers a major real‑world change: engine rewrites yield large speedups (bench.php shows dramatic reductions in runtime) and introduce an abstract syntax tree step that enables faster opcode generation and better static tools. New features include the spaceship and null coalesce operators, scalar and return type hints with optional strict mode, and an Error/Throwable hierarchy so many former fatals become catchable. Upgrades require updating extensions (most must be rebuilt; memcache is a known gap), use phan to scan code, and test on 5.5/5.6 then PHP 7.
