  12. Enhanced Compatibility: PHP 8 maintains a robust dedication to backward compatibility whereas introducing new options. This makes it simpler for builders to improve their current PHP 7 codebases to PHP 8.
  13. Neighborhood and Assist: As PHP 8 turns into extra extensively adopted, it advantages from a bigger and extra energetic group, which suggests extra sources, documentation, and third-party libraries can be found.
