Migrating to PHP 7
summary
Claims ~100% speedup and a completed migration for a large company that included long‑running PHP daemons, with most issues fixed by tooling and small fixes rather than rewrites. Run PHP -l linter, enable error_reporting = -1, use an IDE with inspections (phpStorm mentioned) and the PHP7 compatibility checker, inventory third‑party code and migrate to composer, apply the mysqli shim by Davi Shafiq for legacy mysql calls, aggregate logs (one case drops ~20,000 daily entries to a few hundred), and favor incremental yearly upgrades.
