PHP 5.3 → 8.4
PHP Upgrade Service: from PHP 5.3 to PHP 8.4
Every PHP release drops something your code depends on. We upgrade one minor version at a time, each step a green CI and a mergeable pull request, until you run the latest PHP with strict types and full type coverage.
Typical blockers
What stops a PHP upgrade
- Removed functions and extensions:
mysql_*,ereg,each(),create_function(), dynamic properties - Implicit type juggling that turns into
TypeErrorin PHP 8: string-to-number comparisons, null to internal functions - Untyped code, so static analysis cannot tell you what breaks before production does
- Old dependencies pinned to a PHP version that no longer receives security fixes
How we do it
Step by step, always mergeable
- Intro analysis: we run Rector, PHPStan and our own tooling on your repository to find every PHP-version blocker and estimate the effort per version.
- Bump one minor version at a time: PHP 7.2 → 7.3 → 7.4 → 8.0 and so on. Each bump is a set of small pull requests your team reviews and merges the same week.
- Add type declarations with Rector type-coverage rules, so PHPStan catches the next regression in CI instead of in production.
- Wire Rector and PHPStan into your CI. Your next PHP upgrade takes days instead of months.
What the diff looks like
Every change is a reviewable diff, small enough to merge the same day.
