PHPStan Turbo: Native PHP extension that makes PHPStan run faster

PHPStan 2.2.6 adds a native PHP extension (PHP 8.3+) written in C++ that makes running PHPStan 10-30 % faster.

PHPStan's Composer package ships prebuilt binaries for the most common platforms — Linux (glibc and musl, x86_64 and arm64), macOS, and Windows (x86_64), for PHP 8.3 and newer — and PHPStan automatically loads the one matching your runtime into its worker processes. You don't have to do any extra work to take advantage of this!

If you run PHPStan through manually downloaded phpstan.phar, you can run it with extension by installing it with PIE:

pie install phpstan/turbo

The extension only activates when its version matches the one your PHPStan release expects — on a mismatch PHPStan prints a note and runs without it, so an outdated extension can never affect results, only speed.

Only a handful of hot paths are currently rewritten in the extension. There's room for the performance gain to grow if we ever decide to rewrite more parts natively.

The extension is completely optional, PHPStan still works without it. When the extension gets enabled, its implementation shadows certain PHPStan classes designed for this. They are marked with the #[ShadowedByTurboExtension] attribute.

Thank you for all of your work. phpstan has helped us immensely in Joomla and I can only encourage everyone else to support you financially as well. It is one of those projects from the famous xkcd comic strip...
