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.

Two Ways to Use Path Parameters

Manual Access

$name = $c->getPathParam('name');

Auto-Injection

function(Context $c, string $name) {…}
