phpperf

PHP performance notes, small examples, and phpperf-lint.

Part of XPerf. Shared docs: docs/README.md. Heuristic lint (corpus-ready: yes; ph-array-merge-rebind=error with G4; ph-string-dot-hot=off; ph-echo-hot=hint). Guide v0.

Contents

Focus

Avoid quadratic string growth (.=), prefer push over array_merge rebinding, gate hot echo/print.

Run lint

cd packages/phpperf
php phpperf-lint/phpperf-lint.php path/to/sources
bash scripts/smoke-lint.sh
bash scripts/self-lint.sh

Exit 1 only for error-severity findings (hints exit 0 unless --strict-hints).
