Path Parameters

Dynamic routing with automatic type-cast parameter injection.

{year}/{month}/{slug} placeholders in the route pattern are captured and passed to your handler automatically.

Two access styles — call $c->getPathParam() manually, or let Via inject matching parameters directly into your callback's function signature.

Reflection-based injection matches parameter names to route placeholders. Type-hint int and Via casts the value for you — no manual parsing required.

year: 2025

month: 01

slug: testing

All three parameters auto-injected into the function signature.
