Modern PHP (8.x)
Write PHP the way the 2025-2026 ecosystem does: declare(strict_types=1) at the top of
every file, typed everything, Composer-first, statically analyzed at the top level — not
the way a 2015 WordPress plugin did. This skill owns the language and its
framework-agnostic ecosystem: the type system, Composer + PSR-4, PER-CS style, the PSR
interop interfaces, and the quality toolchain.
Version targeting. Floor is 8.3 (security-only, the lowest you should support).
Default new code to 8.4 (property hooks, asymmetric visibility). Use 8.5 features
(|>, clone with, array_first/array_last, #[\NoDiscard]) only when the deploy
runtime is confirmed 8.5+ — 8.5 released 2025-11-20. 7.x and 8.0-8.2 are EOL; never target
them.
