Why Symfony 7 Matters for Modern Web Development

Key Features of Symfony 7
1. PHP 8.2 and Beyond Support
Symfony 7 fully embraces the latest PHP 8.2+ features. This means better performance, safer typing, and cleaner syntax.
- Native return types are enforced, improving code clarity.
- Read-only classes and properties make data structures more predictable and reliable.
