Rescuing Legacy PHP Projects: Migration and Optimization

•3 min read•By Kimpuler Engineering Team•Enterprise CTO / Backend Lead

Legacy PHP code can be a nightmare—insecure, slow, and hard to maintain. In 2022, we took on a project running on PHP 5.6 and transformed it.

Migration to PHP 7.4

We migrated the entire codebase, fixing critical SQL injection and XSS vulnerabilities. Database queries were optimized, reducing execution time by 70%. The spaghetti code was refactored into a clean MVC structure.

Whether you have a decade-old PHP app or a recent project that needs optimization, we can breathe new life into it.
