I will migrate your legacy PHP code to PHP 8
Alexandr
About this gig
I help businesses and website owners modernize legacy PHP applications so they run cleanly on PHP 8.18.4.
Many older PHP sites break after a server or PHP version upgrade deprecated functions stop working, type errors appear, and the site crashes or shows warnings. I fix exactly that.
My process:
I combine hands-on code review with custom-built tooling that systematically detects and fixes compatibility issues, deprecated functions, and type errors across your codebase even in large files (tested on codebases up to 16,000+ lines). Every change is verified on a real hosting environment (shared/cPanel) before delivery, so you get a working result, not just a report.
What makes this different:
The goal is a seamless backend upgrade your site's design and functionality stay exactly the same. Nothing visible changes for your users; it just keeps working, securely, on a modern PHP version.
Before you order:
Please share the file(s) or approximate line count of code that needs migrating, so I can confirm the right package for your project.
Let's get your site running safely on modern PHP.
