Are there any recommended tools or resources for assisting with the migration of PHP code to a new version?

Migrating PHP code to a new version can be a challenging task, as newer versions may introduce breaking changes that require modifications to the existing codebase. To assist with this process, tools such as PHP_CodeSniffer, PHPStan, and PHPMD can be used to analyze the code for compatibility issues and suggest necessary changes. Additionally, resources such as the official PHP documentation and community forums can provide guidance on best practices for upgrading code to a newer version.
