Upgrade Notes

2.x to 3.x

Version 3 doesn't really attempt to be backwards compatible - I haven't been actively using PHP for some years, so this release is a revived and modernized package for PHP 8, with a smaller scope.

Earlier versions of this package came with a Dispatcher and a URL builder, both of which have been removed from version 3.0.0 of this package:

  • The Dispatcher had no real connection with the Router itself, and was more like a proof of concept than a full-blown implementation - if you wish to upgrade to 3.0.0, you can copy the dispatcher from the old version and use this as a basis for your own dispatcher.

  • The URL builder also had no direct connection with the Router, as has been removed - you can find third-party packages on Packagist specifically for this purpose.

Major breaking changes:

  • Router::resolve() now returns a union type of either Result or Error.
  • Registry is now called PatternRegistry, and Symbol is called Pattern.

Minor breaking changes:

  • Static type-hints were added.

Other than that, what remains is more or less the same.
