What's New in PHP 8.6
Summary
PHP 8.6 adds partial function application, a clamp() helper, a Duration class, and assorted language and stdlib tweaks. The post lists each change without deep analysis.
- Partial function application lets you pre‑bind arguments to a callable, enabling more composable code.
- clamp() provides a one‑line way to bound a number between a min and max value.
- The new Duration class represents time intervals with nanosecond precision and fluent APIs.
- Several smaller improvements include stricter type checks, enum enhancements, and minor stdlib additions.
PHP developers planning to upgrade should know these features to write cleaner, safer code and avoid surprise regressions.
