About this gig

Running an old PHP app that breaks, shows errors, or can't move to a modern server? I'll make it work on PHP 8.x and fix what stops it.


What I do:

  • Find and fix deprecated and removed functions (e.g. mysql_* to mysqli/PDO)
  • Fix fatal errors, warnings, and notices after the upgrade
  • Update old libraries and dependencies where needed
  • Check database compatibility and fix encoding problems
  • Test the main features and report what changed


How it works:

  1. You send the code (or a sample) and your current and target PHP versions
  2. I review it and confirm scope and price
  3. I work on a copy, never on your live site
  4. You receive the updated code and a short change report


Please message me before ordering with your PHP version, framework or CMS (if any), and approximate size of the app.
