Unveiling PHP 9.0: What's in Store?

Deprecated Features Removal:

PHP 9.0 is set to remove features that have been deprecated in previous versions (8.1 to 8.4). This step, though leading to breaking changes for some, is a stride towards modernization and efficiency.

The introduction of DNF types in PHP 9.0 allows for a combination of union and intersection types, providing more flexibility in type specification and handling.

Constants in Traits:

PHP 9.0 extends the usability of traits by allowing the definition and use of constants within them, enhancing the capability of these reusable code blocks.

Redact Sensitive Parameters in Backtraces:

This feature allows developers to mark sensitive parameters, preventing their accidental exposure in error backtraces, a crucial step for security in production environments.
