composer require --dev "rector/rector": "^1.0"

One of the most significant tools of the latest time. Brings automated code refactoring and clean up at your finger tips.

Need to upgrade your PHP version? It gets you covered. Want to apply fancy null-coalescing operator instead of ancient isset calls? Here you go. Need an upgrade for specific framework? It has custom pluggable rules for that. Your case is too specific? Write your own rule and you're good to go.
