FAQs

While not strictly required, tools like PHPStan or Psalm help enforce PHP 8 features and catch issues early. Updated IDEs (like PhpStorm or VS Code with PHP extensions) also provide syntax support and autocompletion.

str_contains() and the nullsafe operator (?->) are the quickest wins. They clean up common code patterns instantly with no downside.

Yes. Enums provide type safety, which constants don’t. They ensure only valid values can be used, making your code safer and easier to maintain.

Not necessarily. JIT mainly benefits CPU-heavy tasks like data processing or scientific calculations. For most web apps, performance gains will come more from I/O optimizations (like caching or database queries) than from JIT.

No. PHP 8 is backward compatible with most PHP 7 code. You can adopt features incrementally—start by using new syntax in fresh code and refactor older parts gradually over time.

Yes, many organizations transition existing Drupal sites into headless setups. It usually involves reworking the frontend to consume Drupal’s content via APIs while keeping the backend for content management.

Organizations that need multi-channel content delivery, want to leverage modern frontend frameworks, or require top-tier performance and scalability are strong candidates.

In many cases, yes. By decoupling, the frontend can be optimized independently—often deployed as static files on a CDN—resulting in faster load times and better SEO performance.

Yes, it typically requires more development expertise since the frontend and backend are managed separately. However, the added flexibility and scalability often outweigh the initial complexity.

Custom modules should be placed in the modules/custom directory. This keeps them separate from core modules (in core/modules) and contributed modules (in modules/contrib), making upgrades and maintenance easier.
