Do you handle PHP runtime upgrades too?

Yes. PHP runtime upgrades are often bundled with Laravel upgrades because Laravel version requirements determine the minimum PHP version. We handle PHP 7.4 to 8.3, PHP 8.0 to 8.4, and similar runtime upgrades as part of the engagement. This includes Composer constraint updates, deprecated PHP syntax cleanup, type hint modernisation, and runtime configuration updates on the deployment infrastructure. The PHP upgrade is sequenced before or alongside the Laravel upgrade depending on the specific path.
